o PREFACE , 1 In a general sense, the term "de minimus" refers to concentrations or quantities of potential pollutants that are present in so minute amounts in a gaseous, liquid or solid waste as to be relatively harmless to man and his environment. In other words, a waste or effluent that meets criteria defining "de minimus" levels should be acceptable for disposal or release without any special precautions or monitoring programs. ~ While wastes and effluents from power reactor operations are generally thought g of in terms of their radioactivity content, the concept is equally applicable to such environmental concerns as free residual chlorine, atmospheric and aquatic rejection of waste heat, and the impingement and entrainment of aquatic organisms in cooling water systems. The concept of "de minimus" concentrations of radionuclides in slightly contaminated solid waste was first brought to our attention about two years ago by several of NESP's sponsors and the Nuclear Regulatory Comunission. When funding became available in mid-1977, Nuclear Safety Associates was awarded a contract to investigate existing standards for radioactive Imaterialsandothercons q purpose of identifying criteria that define "de minimus" levels. Once the criteria were defined, the thrust of the study was to develop and apply a generic methodology that could be used for determining whether or not certain slightly contaminated solid wastes were suitable for a "de minimus" radioactivity-level classification. It is important to note that it was not intended for this investigation to include an evaluation of the overall acceptability or appropriateness of various existing radiation standards or guidelines, such as 40 CFR Part 190 and Appendix I to 10 CFR Part 50, but rather, to use current lii

, regulations as a basis for defining reasonable "de minimus" levels. Hence, i

it should not be inferred by the reader that the results of the study -

tacitly endorse the regulations considered. Also, the criteria are presented l as a suggested approach to defining "de minimus" levels and do not necessarily represent a consensus position of the nuclear power industry, __ For this initial NESP investigation of the "de minimus" concept, PWR i spent secondary-side powdered resin was selected as a specific and timely subject that could be used to demonstrate the development and application of a generic methodology. The study was limited to spent powdered resin because of budgetary constraints and the fact that the spent resin exampla would suitably serve the purpose of illustrating the basic concept. It was found that the methodology is applicable to other solid wastes, e.g.,

 *}                                         slightly-contaminated soils, dredge spoils and the like. However, because the pathways for dose to man evaluated in this work were selected on the l

basis of solid waste, the methodology is not complete in terms of its application to wastes other than solids. In the particular case of the - t

                                            " trash" category of solid wastes, the methodology is probably incomplete l                                       because of the possibility of incineration and the fact that the methodology l                                       does not include this kind of airborne pathway to man. Nonetheless, this should not be interpreted as a major shortcoming in the methodology, because 23                                         once the user understands its application to solid waste, he can readily include analyses of additional pathways that are relevant to the particular

! waste being examined. The limiting radionuclide concentrations for solids presented in this work are thought to be generic and independent of site-specific variables. iv

4, , 4 For this study, pathways and assumptions were selected in order that variations in individual site characteristics would not appreciably alter the findings. For example, the assumptions made for the " sanitary landfill-leaching into watercourse" pathway analysis, which would usually be consi-dered quite site dependent, were sufficiently conservative that even the limiting radionuclide concentrations stipulated for this pathway can be considered independent of site-specific features. It is also important to recognize that the primary criterion identified in this study for determining "de minimus" levels, which is 1 ares / year to an individual, was selected on a very conservative basis, and that higher levels of contami-nation are very likely to be appropriate for some applications of the concept, particularly those involving more controlled waste disposal

1.0 INTRODUCTION

In 1977, the National Environmental Studies Project of the Atomic Industrial Forum established a task -force to develop the scope of a study aimed at determining levels of radioactivity which could be considered "de minimus", i.e., levels which could be considered "non-radioactive" and such that materials at or below these levels could be released or discarded without restriction. As a result of the work of this task force Nuclear Safety Associates was commissioned by the Atomic Industrial Forum to carry out such a study, to develop specific recommendations for quantitative "de minimus" levels using spent powdered ion-exchange resins from PWR secondary systems as an example, and to supply the technical and s scientific bases for determining and justifying the levels selected. In the development of the "de minimus" values reported herein, the i following basic steps were used: e Basic radiation protection criteria were identified. Clearly there is a direct relationship between the quantity or concen-tration of radioisotopes which may be released by any means and the degree of protection which is to be provided to members of the public. Therefore, it is first necessary to establish what the desired degree of protection is. The selection of this criterion is discussed in Section 3 of this report. e Pathways by which released activity could reach man were identified and described. The major modes by which man may be exposed to ambient radioactivity are: ingestion, inhalation, and direct irradiation. There are also a number of transport mechanisms by which radioactive material may move in the 1 i

environment and thus reach man. Some of these are: suspension of solid particles into air, surface runoff with water, transport by groundwater, and physical transport into situations wherein food products may be raised in proximity to the radioactivity. A matrix of exposure pathways was set up to ' describe all practica-

ble ways by which exposure of man might occur. A discussion of the pathways investigated is given in Section 4.2. e For-each pathway and for each isotope the limiting concentration kl which allows the selected radiation protection criterion to be met was cal'eulatsd. For ,each radionuclide the limiting pathway was determined and the radionuclide limit was set, individually, based upon the most restrictive mode found for that nuclide. A discussion of this calculational technique and of the computer code developed to carry it out Ds given in Section 4.3. The extensive calculational results are summarized in Section 4.4. ' s Consideration was given to whether application of the principle . as low as is reasonably achievable (ALARA) would result in limits lower than those resulting from the calculations identified above. I It was concluded that ALARA did not result in lower ILsits than N l those calculated herein. e The "de minimus" limits discussed in Section 4 are then applied to a specific case--the disposal of PWR secondary resins. In a specific case, it it possible to compare activity levels to the "de minimus" levels calculated herein and to determine the key radionuclides which dominate that specific case. This is ! discussed in Section 7.1. Finally, the practicality of the l l specific application is addressed by considering whether the i 2 L

normally available analytical capability is able to determine these key isotopes at the required low levels. This is considered in Section 7.2. The result of this study is the determination within defined con-ditions of concentrations of essentially all isotopes of interest to the nuclear industry which can be considered "de s:inimus." The appli-cation of the general method to a specific case is illustrated. It'is believed that the method is applicable to a wide variety of materials and situations.

2.0 CONCLUSION

S The~ major conclusions from this investigation are:

1) A suggested appropriate level of protection to be used in establishing "de minimus" concentrations of materials containing trace amounts of radionuclides is a maximum total body dose of 1 arem/ year, or a maximum dose to any organ of 3 arem/ year, to any individual. This level is suggested by the application of 9 the 10 CFR Part 20 provision which permits ignoring isotopic contributions which individually contribute less than 10% to the total dose and which collectively contribute less than 25% to the design guide levels of 10 CFR Part 50, Appendix 1.

2) For wastes such as PWR secondary resins disposed in soils, it has been shown that four isotopes, Cs-137, Cs-134 Co-60, and Co-58 clearly dominate the dose calculations. Two of these, Co-60 and Cs-137, could be used as " keys" to establish compliance ,

, g             with the suggested limits.

3) The concentration levels required to meet the suggested "de minimus" concentrations are in the range of one pCi/ gram. For the " key" isotopes, Co-60 and Cs-137, these concentrations are readily measureable with equipment normally available at nuclear reactor sites.

A direct relationship will exist between the concen-trations of radioisotopes which may be disposed of without specific controls, i.e.,     be considered "de minimus= and the degree of protection provided to members of the public.

Existing radiation protection standards are not applicable to routine unrestricted disposal of slightly contaminated nuclear materials. They a do, however, serve as references from which to derive "de minimus" criteria compatible with regulatory standards. The potential for individual and population exposure via any single source should be considered in relation to exposures from other sources. - particularly from naturally existing ones. The relative benefits of pro- , viding protection against radiation from a specific source may also be judged in perspective with variations in personal exposures from back-ground sources. Therefore, the radiation protection criteria appropriate for deter-mining the concentrations of radioactivity in slightly-contaminated materials which may be disposed of in an unrestricted manner must be compatible with current or revised standards for protection against radiation. They should also retain perspective in relation to the risk of health effects from natural environmental exposures and variations therein. 5

3.2 Natural Background Radiation Exposures The significance of any added exposure potential associated with introduction of radioactivity into the environment should be considered in relation to natural environmental levels'of radiation and variations therein. A review of natural sources of radiation exposure and their variability can provide guidance and perspective for selecting the boundary of "de minimus" dose rates from release of radioactive material into the environment. C)

     '  Sources of Natural Radiation Naturally occurring radiation in the environment originates from cosmic rays, radionuclides produced by cosmic rays, and from primordial radionuclides in the earth. In the United States, the air dose rates due to cosmic rays vary from about 27 to 95 mrad /yr and the population weighted mean air dose rate has been estimated to be about 29 mrad /yr l

i (NC75). Outdoor exposure rates due to terrestrial radioactivity vary , l from about 12 to 90 mrad /yr in the US and the population weighted mean is about 44 stad/yr (NC75). C) People are also exposed to natural radiation by internally deposited radionuclides that have been inhaled or ingested as well as to external irradiation. Typical dose equivalent rates to a representative US resident from naturally occurring sources are provided in Table 3-1.* The estimated dose rate from cosmic rays includes a ten percent reduction to account for structural shielding. Irradiation by primordial terrestrial radioactivity includes a 20-percent reduction for shielding *by housing and

i a 20 percent reduction for self-shielding by the body. The dose to the lung from inhaled radioactivity is tabulated separately; doses to other tissues from inhaled radioactivity are included with other primordial radionuclides in the body. Estimated doses to the gastrointestinal tract do not include any contribution from radioactivity in the contents of the tract. Environmental Variations , Individuals and population subgroups within the United States expe-rience dose equivalent rates which vary widely from the average. Large segments of the population experience appreciably different natural exposures. External terrestrial dose equivalent rates experienced by people indoors range from about 15 arem per year on the Atlantic and

   ,       Gulf Coast plain to 30 arem per year in mid-continent and to about 55 1

arem per year along the Colorado Plateau (Oa72). Cosmic ray dose equivalent rates experienced by the population range from 26 arem in Florida to about 50 arem per year in Denver, Colorado (NC75). Thus natural external radiation doses to large groups in the United States population vary from about 41 to 105 ares per year by geographic location alone. Most of the variation in dose due to radionuclides in the body 1 results from variations in Ra-226 in drinking water and in the lung from Rn-222 progeny. A typical United States resident receives about 16 arem per year bone dose and about 0.2 arem per year to soft tissue from ingested radium (UN72). Even if the radium concentration in community water l 1 supplies does not exceed the current regulatory limit of 5 pCi/1 (EPA 76), 7

dose rates experienced by users could be as much as 1 arem per year to soft body tissue and about 150 arem per year to bone from drinking water alone. An average dose.to the lung of about 100 arem per year from radon progeny inhaled in dwellings has been attributed to construction mate-rials, type of construction, ventilation, and radioactivity in land beneath (NC75). Variations among these influential factors cause lung dose equivalents to vary by a few hundred millirem per year among g limited population groups in the United States. i Throughout history, mankind has been exposed to roughly these levels lg 'f of naturally occurring radiation. In some other parts of the world exposures have been even higher. For instance, along the southeastern i coast of India, where thorium-bearing monazite sand is abundant, external I exposures tc residents from natural radioactivity in the sedy soil In some towns along the ranges up to about 2000 millirads per year. coast of Brazil, external exposures from monazite sand in the soil average 550 millirads per year within a range from 90 to 21,00 millirads annually (UN72). Even at these rates, effects on man's health or l development have not been detected. l Variations Accordina to Livina Habits. Differences in personal i . living habits also affect exposure to naturally occurring radiation and radioactive material. Within a given locality the construction materials and style of buildings influence indoor radiation exposure rates. Camma exposure rates in masonry (Oa72) and in slab-on-grade dwellings (Fla77) have been observed to be about the same as in natural outdoor areas surrounding the dwellings. But in wood frame dwellings, gamma exposure rates ranging from 70 to 80 percent of outdoor

. 8

levels and averaging closer to 70 percent have been observed (Oa72). Yeates (Ye72) measured gamma radiation intensity reductions of about 25% on the first floor and about 50% on the second floor of wood frame houses. Overall, the difference in direct radiation exposure to persons living and working in woodiframe buildings rather than in concrete or masonry buildings can be about 10 millirem per year. Lung exposure to radon and its progeny may be affected significantly by living habits. For instance, concentrations of Pb-210 and Po-210, both long-lived progeny of Rn-222, have been found to be about 2 or 3 times higher in the lungs and ribs of cigarette smokers than in non-smokers (Ra64, UN72). This amounts to 6 to 9 millirem per year additional I dose to the lungs of a smoker, a 5 to 7 percent increase in total lung dose by comparison with a typical non-smoker. If natural gas is used in a residence, lung doses will typically increase by about two percent,

                .i.e.,          about two milliram per year, as a result (Ba73). Perhaps the greatest influence on naturally occurring lung exposures is ventilation -
,                practices in dwellings which alone can influence radon and radon progeny i

concentrations in a house by a factor of as much as ten (Wi77). Acother activity which affects exposure to naturally occurring radiation is air travel. At the jet cruising altitude, about 33,000 to t 39,000 feet, the dose equivalent rate due to cosmic rays is about 0.3 to 0.5 arem per hour. Based on this, the United States population averaged dose equivalent from commercial air travel is about one millirem annually. However, if a person travels more frequently, e.g., two trips per month of four hours dur.stion each, his annual dose equiva1ent will ! be increased by about 30 to 50 millires. 9

Where one vacations may also influence his annual radiation exposure. Spending a week skiing in Colorado will deliver about 1.5 millirem more than a week at an Atlantic beach, for instance. These examples illustrate the effects personal living habits can have upon exposure to naturally occurring radiation and radioactive material. The range and variation in human exposure to natural radiation as consequence of living habits and locations are illustrated in Figure 3-1. Implication of Natural Background Exposure Knowledge of population exposure rates from naturally occurring radiation and radioactive materials provides a rational basis for selecting appropriate standards for unrestr.icted disposal of slightly radioactive material. It should be remembered that the doses from natural radioactivity l and, to a large extent, from medical administration, affect the entire, United States population. Conversely, the number of people arposed to In fact, a "de minimus" concentrations of radioactivity will be small. limit on the potential dose to maximally exposed persons should be an i adequate criterion for determining appropriate "de minimus" radionuclide concentrations. At such a low individual dose rate, a cost-benefit interpretation based on an estiaste of population integrated dose equivalent would be of questionable value in providing guidance (IC73, NC75a). The range and variation in exposures to natural sources of radiation experienced by the population of the United States suggests "de minimus" dose rate of a few millirem per year to individual members of the 10

population are appropriate. For example, three millirem total body l dose per year is well within the variation among residents of a given i area and is only a few percent of the variation among large groups of people in different parts of the United States. l 3.3 Unregulated, Man-made Radiation Exposures The largest fraction of the man-made radiation expositre to resi-dents of the United States is now administered in the practice of ' tr medicine and dentistry. Public exposure from this source exceeds that from other man-made sources by ten to one hundred times. Medical i diagnostic radiology accounts for at least 90 percent of the man-made radiation exposure. Estimates based on the 1970 X-Ray Exposure Study were that the per capita mean active bone marrow dose to adults in 1970 The was 103 millirem from all diagnostic radiology procedures (Sh76).

  .'-       mean abdominal dose per capita in the US population in 1970 from medical and dental radiation was estimated to be 72 millirem (Gi72). Medically-administered radiation doses vary widely among individuals, of course.

These estimates of localized doses are roughly equal to the average total body dose a US resident receives annually from natural radiation sources. l Jg 3.4 Existing Regulations As a first step in establishing radiation protection criteria associated with "de minimus" releases, the existing regulations were reviewed. Some aspects of these regulations could be interpreted as establishing "de minimus" concentrations of radioactive materials for disposal. These relevant Federal regulations which influence the 1 i choice of radiation protection criteria for establishing "de minimus" l l concentrations were examined. 12

r. ,

federal Regulations, Title 10, Part 20 . The maximum exposure in unrestricted areas permitted by 10 CFR Part 20 is 500 mrem per year to the whole body of any individual (10 CFR Part 20.105). For a population group, the exposure from radioactive materials in effluents may not exceed that which would occur if the group were continuously exposed to air or water concentrations containing one-third of the unrestricted Maximum Permissible Concentration (MPC) (10 CFR Part 20.106). These limitations are subject to the further constraint I that the exposure must be as low as is reasonably achievable (10 CFR Part 20.01). Part 20 also restricts the method of waste disposal (10 CFR Part I 20.301-305). Disposal into a sanitary sewage system is not allowed unless:

1) the waste is readily soluble or dispersible in water.

2) the daily discharge is less than the larger of:

a) the quantity which if diluted by the average daily quantity of sewage would result in an average concentration equal to. the unrestricted MPC in water, or b) ten times the quantity of such material specified in Appendix C of 10 CPR Part 20

3) the monthly average discharge concentration is below the unrestricted MPC in water, and

4) the gross discharge is less than 1 curie per year.

Burial of waste in soil is restricted by 10 CFR Part 20.304 to 12 burials per year or less at a minimum depth of 4 feet with successive burials separated by distances of at least 6 feet. The total quantity l buried at any one location and time may not exceed, at the time of l 13

burial, 1000 times the $sount specified in Appendix C-of 10 CFR Part 20. The Appendix C values for several of the key isotopes are: Cs-134 1 microcurie Sr-90 0.1 microcurie Cs-137 10 microcuries Ra-226 0.01 microcurie Co-60 1 microcurie l Thus the inventory at any disposal location may be 1 millicurie of Co-60 or Cs-134 or 10 mil 11 curies of Cs-137. Since for mixtures, the sum of the ratios of the quantity present to the inventory allowed must g

   *!       be less than or equal to one, the actual amounts of these isotopes allowed would be lower. For mixtures of beta emitters of unknown l

composition, the total inventory limit would b'e about 100 nanocuries, i There are no specific guidelines in 10 CFR Part 20 pertaining to disposal at sea or to incineration. They are handled on a case by case basis as provided for in Parts 20.302 and 20.305. Federal Rerulationc. Title 10. Part 30 A person may receive, possess, use, transfer, own, or acquire materials containing byproduct radioactive material and be exempt frem the requirements for a license providing the activity concentrations of j '

          -  byproduct material do not exceed those listed in 10 CFR Part 30.70 Schedule A (see 10 CFR Part 30.14). However, the introduction of by-product material in exempt concentrations into materials and transfer of ownership or possession of it does require a license in accord with 10 CFR Part 32.11. Some limitations are stated in Part 32.11(c).

Federal Regulations. Title 10. Part 50 Appendix I Appendix I to 10 CFR Part 50 provides numerical guides for reactor design objectives and limiting conditions of operation. The applicant 14

must provide reasonable assurance that the following design objectives will be met for each reactor. Total annual radioactive releases in liquid and gaseous effluents above background from a single light-water-cooled nuclear reactor must not cause the estimate of annual dose or dose commitment to any person in an unrestricted area to exceed:

1) 3 arem to the total body or 10 arem to any organ as a result of activity in liquid effluent,

2) 5 area to the total body or 15 arem to the skin due to activity in gaseous effluent, and

3) 15 arem to any organ from radioactive iodine and radioactive material in particulate form released to the atmosphere.

i In addition to meeting these design objectives, the radweste system must include all items of reasonably demonstrated technology, that when added to the system sequentially and in order of diminishing cost-benefit s return, can for a favorable cost-benefit ratio effect reductions in dose to the population reasonably expected to be within 50 miles of the - reactor. The interim value of $1000 per total body man-rem and per man-thyroid-rem is currently accepted in the cost-benefit analysis. Operating reactor guidelines are set at one-half of the design

'f]          objective annual exposure based on actual releases in affluents during any calendar quarter. They represent design objectives for releases to the environment which are controlled and acnitored prior to release and are the object of environmental monitoring after release.

These requirements apply to liquid and gaseous effluents of a single light water reactor, but they are not directly applicable to solid wastes. However, they do provide guidance in determining "de minimus" levels for solids. 15

1 l Since "de minimus" wastes would not be subject to environmental surveil-lance af ter disposal, lower activity concentration limits in "de minimus" wastes than in reactor effluents may be justified, even though, in view of variations in natural radiation background levels, Appendix 1 design guides may be too low in the first place. Federal Regulations, Title 10, Part 71 i Because it is likely that "de minimus" waste will have to be trans-

   -   ported, it is important to recognize the requirements of 10 CFR Part 71 for special packaging. Compliance may be guaranteed is the activity concentration is less than 2 nanocuries per gram or if each package contains less than 50 mil 11 curies, the exempt quantity for mixed fission r

l products. Assuming 50 millicuries are packaged in a 55-gallon drum at a f density of 1.5 gram per cubic centimeter, the activity concentration could !- be as high as 160 nanocuries per gram. As will be shown later, this ! limitation is higher than that calculated herein as "de minimus." . Federal Regulations, Title 40, Part 190 The maximum annual exposure allowed by 40 CIR Part 190 to a member of the public as the result of planned discharges of radioactive material t to the general environment from uranium fuel cycle operations is 25 arem f to the whole body, 75 area to the thyroid, and 25 area to any.other organ. l These limitations exclude operations at waste disposal sites, but do not specifically exclude waste itself. However, the much lower limits of 40 CFR Part 190 make it clear that any attempt to use the exposure limits of 10 CFR Part 20 as a criterion for "de minimus" waste disposal will be unacceptable. 16

         .. ..                                                                               1 Proposed Federal Guidance on Transuranium Elements in the Environment The Environmental Protection Agency has proposed Federal radiation protection guidance on limits of dose to persons exposed to transuranics in the environment as a result of existing or possible future unplanned      I contamination (EPA 77). The text of the proposed guidance follows:

1. The annual alpha radiation dose rate to members of the critical segment of the exposed population as the result of exposure to transuranium elements in the general environment l should not exceed either:

k a. I millirad per year to the pulmonary lung, or and

b. 3 millirad per year to the bone.

2. For newly contaminated areas, control measures should be taken to minimize both residual levels and radiation exposures of the general public. The control measures are expected to result in levels well below those specified in paragraph one.

Compliance with the guidance recommendations should be achieved within a reasonable period of time.

 ,                   3. The recomumendations are to be used only for guidance on possible remedial actions for the protection of the public health in instances of presently existing contamination or of possible future unplanned releases of transuranium elements.

They are not to be used by Federal agencies as limits for 1 planned releases of transuranium elements into the general environment. One " millirad per year to the pulmonary lung" is meant to be the equi-librium dose rate resulting from chronic inhalation. The corresponding dose equivalent rate for alpha emitting transuranics is 20 millirem per year. 17

9 0 3.5 Selection of Dose Limits Appropriate for "de minimus" Disposal Concentrations Concentrations of radionuclides which may be considered "de minimus" are directly related to dose limits which are appropriate for unrestricted i disposal. That is, selection of such limits should be guided by criteria I which reflect an acceptable level of health protection. A rational conservative criterion for selecting "de minimus" dose limits is to select the level below which the dose rate to maximally l EP l exposed individuals is insignificant in comparison to the dose rate ! typically experienced by a member of the population from naturally

  *"-{

l I l occurring radiation and radioactivity. Considering the natural dose

rate distribution in the USA, a few millirem per year more or less - 3

  'cx   for instance, is not significant in comparison with the dose rate dis-i     tribution from natural sources.
  ..-          A practical criterion is that the dose limits selected must be l      . compatible with existing radiation protection standards and regulatio'ns j

or must suggest appropriate revision of the regulations. To this end, practicality dictates the "de minimus" dose rate limit be no more than 10 CFR Part 50, Appendix I design objectives and possibly less. That h is, to be consistent with existing regulations, the "de minimus" dose limit should not exceed 3 (liquid) to 5 (airborne) millirem total body dose equivalent per year to individual members of the public. Practical guidance for selecting "de minimus" dose levels can be deduced from 10 CFR Part 20, Appendix B. According to Appendix B, footnote 5, a radionuclide in a mixture may be ignored it if is present 18

in less than 0.1 of its maximum permissible concentration and if the sum of the fractional MPC of all radionuclides considered as not present in the mixture does not exceed 0.25. A "de minimus" dose rate limit is then suggested by the combination of the Appendix I design objectives and the 0.25 factor of disregard given in 10 CFR Part 20, Appendix B. Together. 0.25 of 3 to 5 arem per year total body dose is roughly one arem per year. Consistent with 10 CFR Part 20, the corresponding individual organ

       ,               dose limit would be 3 area per year.       One millirem per year to the total N                     body or 3 to individual organs is hardly significant in relation to doses received from natural background sources.

J To further illustrate its insignificance, assuming the linear non-threshold dose-effect relation and the dose-to-risk estimates presented in the BEIR Report (BEIR72) hold at such a low dose rate, the additional risk associated with continuing doses of one arem per year is estimated to be about one additional chance of adverse health effect in ten million person-years of exposure. It should be acknowledged that this extremely ~ l low estimate of hypothetical risk is probably an unrealistic overestimate of actual risk and may not be useful for other than illustration (see NC75a, pp. 3-4). Nevertheless, it is insignificant in relation to many

.+.

demonstrated risks a typical resident experiences in the course of daily j living in the US. By comparison, the US mortility rate in 1973 attri-l buted to motor vehicles was 265 per million person-years and that attri-buted to falls was 80 per million person-years. Therefore, one millirem'per year total body dose equivalent and 3 millirem per year single organ dose equivalent in excess of the natural radiation background are suggested as dose equivalent rates at and below l i i i 19

which the dose rate to persons maximally exposed to radioactivity in solid waste should be acceptable as "de minimus." This radiation protection criterion was selected for use in connection with this study. I If higher values than one millirem total body and 3 milliram to an organ are selected as de minimus" dose limits, then the concentrations pre-sented herein would be scaled upward directly. i ei

4.0 METHOD 01DGY DiPLOYED In this study, solid wastes with very low activity concentrations are postulated to be placed in the environment with and without controls ordinarily imposed by regulations applicable to disposal of non-radio-active solid wastes. For voluminous solid material, land disposal is anticipated. One objective of this study was to develop,a methodology to quantify the relation between the "de minimus" radiation protection

 ;       criteria selected and the corresponding limiting concentration of each

'8Pd radionuclide in solid waste which allows the radiation protection 9 criteria to be satisfied. The relation would be determined by environ-mental pathway analyses. 4.1 Disposal Scenarios During the study, several disposal scenarios were considered with the objective of selecting those which are likely to have the most potential for maximum personal exposure to radioactive material in . the environment from the discarded solid waste. Examination of potential [ environmental pathways and survey calculations suggested that land disposal [ t with residents on the disposal site probably leads to the maximum hypo- ,b thetical personal exposure. It should be noted that neither disposal at sea nor a disposal scenario that primarily produces airborne dispersion, e.g., incineration, was considered. Only the two scenarios which appear to have the most potential for maximum individual exposure were examined in detail. In one, identified as the " sanitary landfill" scenario, dis-

card into a sanitary landfill with ordinary operating procedures in effect was postulated. Construction of a dwelling on the sanitary landfill was assumed to occur five years after operation of the sanitary landfill has l 22 j .__ _ _ ._.

e e ended. In the other scenario, termed " fill wanted" disposal, unregulated use of the solid waste as landfill in a residential setting was postulated. In the latter case, a dwelling was assumed to exist on the landfill immediately after placement of the waste. 4.2 Environmental Pathways An array of possible environmental pathways is associated with each disposal method. In this study, one requirement was to conceive feasible p disposal scenarios with which the most important pathways are associated hf' and to evaluate all of the associated pathways in a way which determines the critical pathway for each radionuclide in discarded waste. The application of the methodology developed in this study was confined to land disposal of a homogeneous, bulk solid waste, namely spent, powdered ion exchange resins from PWR secondary systems. Man's most direct radiation exposure from discarded solid waste could be by irradiation during or after its placement in a landfill. I Ingestion of a small amount of waste or inhalation of material suspended in the air can also be direct pathways. g Other exposure pathways involve environmental transport mechanisms. Digging in a landfill may redistribute some of the material and cause some suspension in the air. If food crops are grown on a landfill that has not been covered adequately, plant uptake of radionuclides from the fill material may establish a link to man via vegetation and/or meat. Leaching followed by surface or ground water migration or erosion and transport by wind or water all create additional pathways to man where contact by external irradiation, ingestion, or inhalation are possible. 23

f The evaluation of many environmental pathways is not h'eavily dependent upon site specific data. The evaluation of pathways involving hydrologic transport, namely groundwater migration or a surface stream is dependent on values of site releted variables, however. To avoid site dependency, surface water and ground water migration were not modeled. Instead, a conservative choice of one percent of radioactivity in vaste discarded was assumed to leach directly into a watercourse, per year. For dilution a stream flow of 10 liters per second was assumed. ! GWP The effect of any other stream flow on estimated doses would be in b-inverse proportion to the nominal stream flow assumed. d l Potential dose equivalent rates associated with the sanitary land-

               -   fill and the fill wanted disposal scenarios were evaluated with environ-I                   mental pathway models suggested in Regulatory Guide 1.109. Revision 0 (RG 1.109) except as mentioned for hydrologic pathways. Specific assumptions and values of variables assigned in the pathways evaluation are stated in Appendix B for each pathway examined in the " sanitary land-fill" and " fill wanted" disposal schemes. Otherwise, values suggested in Regulatory Guide 1.109 for individuals were assigned. An example of l

d- specific assumptions, taken from Case I-A for the evaluation of postu-C.1 () ~ 1sted leaching of radionuclides from solids in-a sanitary landfill to a l ) watercourse is shown in Table 4-1. Detailed assumptions used in all the 1 other cases and the computed results of the pathway analyses are included in Appendix 5. Bulk solid waste containing traces of radioactivity offers the most potential for individual exposure when used as landfill around a residence. Generally, the most direct exposure pathways were found to offer the 1 l greatest potential for exposure of persons nearby. 24

9 Ordinarily, radioactive material released as effluents is not assumed to perturb natural background exposure rates. However, bulk solids which, in isolation, contain "de minimus" concentrations of radioactivity, may actually reduce natura1 background exposure rates at the disposal location by shielding, displacing, or diluting the i naturally radioactive environmental media (soil, etc.). Since the criterion selected for determining a "de minimus" concentration limit, i.e., natural background exposure rate plus an increment of one millirem /yr

       ;          total body or 3 millirem /yr to any single organ, is so restrictive          ,
     ~

perturbation of the natural background exposure rate at the disposal location may be a significant factor. For each millirem /yr reduction in natural background exposure rate caused by the presence of solid wastes,- the contribution of the subject waste to the total exposure rate (from background plus waste) could conceptually be allowed to increase by one millirea/ year without causing an environmental impact i in excess of that corresponding to the criterion. Notwithstanding the likelihood that disposal of "de minimus" wastes may well result in a diminution of natural background radiation, no credit for this fact hh was taken in these calculations. 4.3 Calculational Technique The general approach used to determine the "de minimus" concen-l trations was to first cateulate the limiting radionuclide concentrations for each pathway separately. Then for every nuclide and pathway consid-ered, a search of all pathways was conducted to find the pathway which resulted in the most restrictive disposal limitation for each radio-nuclide. These values represent the solution to the problem of deter-mining "de minimus" concentrations. 25

A computer program was written to execute the above general pro-cedure. Each pathway was represented by a subroutine which calculated the limiting concentrations for that pathway for the values assigned the variables. The limiting concentration was determined for each nuclide as if it were the only nuclide contributing to the dose rate with the exception that the dose rate associated with daughter products were charged against the parent nuclide. This was accomplished by assuming the initial concentration of each radionuclide in the waste was 1 pCi/g. Then for each F pathway, the dose equivalent rate associated with each radionuclide and l l its accumulated decay products'at the time of exposure was computed.

l. Each computed dose equivalent rate and the associated activity concentration initially in the waste were scaled up or down to match the appropriate "de minimus"' dose rate limit. In order to conservatively estimate doses, radioactive decay products were assumed to be transported with their parent in every pathway until taken into plants or animals. At that point, the stable element transfer data or bioaccumulation data in r Regulatory Guide 1.109 were used where appropriate. Detailed equations l

used to evaluate each exposure pathway are given in Appendix A. After the limiting concentrations for each pathway were calculated, the program selected the critical pathway of each nuclide. Finally, a table was generated, e.g., Table 4-3, which shows the limiting concentration for each critical pathway and the "de minimus" concentration limit with i

  -      the associated most limiting pathway.

4.4 Results of Calculations Individual Pathway Evaluation Each disposal scenario-pathway-receptor (total body or organ) combination was computed independently to determine the "de minimus" concentration limit of each radionuclide in that case. Table 4-2 is an example of the results of calculations for one case, leaching from a sanitary landfill into a watercourse with a transit time of one year. Quantities assigned to environmental variables in the computer code are listed at the end of Table 4-2 and in Table 4-1.

T A total of 143 separate disposal scenario-pathway-organ combinations were evaluated in four series of cases. They are identified by: M Series Disposal Scenario Receptor of Dose I Sanitary Landfill Whcle Body II Fill Wanted Whole Body III Sanitary Landfill Critical Organ..

IV Fill Wanted Critical Organ I
Computational results of 15 of these separate cases appear in Appendix B.

In each of the tables, the limiting concentration of each radionuclide is expressed in units of microcurie per gram. Entries appearing as 7

1E07 pCi/gm represent concentrations greater than 1 x 10 pCi/gm of I~ waste. This value, equal.to 10 Ci/gs, was chosen arbitrarily as an upper cutoff value. Eummary of Most Limiting Cases Af ter the limiting activity concentration of each radionuclide in each disposal scenario-pathway-receptor combination was calculated, the program selected the critical pathway of each radionuclide associated with any of the combinations evaluated. Finally, a table was generated, l 28

e.g., Table 4-3, which shows the limiting concentration, i.e., the , activity concentration of a radionuclide which may produce the "de , minimus" dose limit, in each of the most important pathways associated with any of the disposal scenarios evaluated. The table also lists the "de minimus" concentration limit of each radionuclide along wich-its critical pathway. The tabulated values of the~"de minimus" concentration limits, in Table 4-3 for instance, represent a general solution to the N problem of determining "de minimus" concentrations based upon the most restrictive disposal scenarios and environmental pathways conceived.

    ;                  The results shown in Table 4-3 are repeated in Table 4-4 but with the nuclides arranged in order of increasing "de minimus" concentration limit.

The lowest "de minimus" concentration limits is that of Ra-226, and its critical pathway is through a child eating some of the discarded resin. However, it is not a significant or limiting constituent of .

reactor wastes. The next most nearly limiting radionuclides, all of

which have "de minimus" ccacentration limits below the pCi/ gram level are:

The use of the " fill wanted" scenario (Series II and IV).results in limits somewhat lower than would occur if it were assumed that the "de minimus" waste were disposed of in a sanitary landfill. If the 29

5.0 COST-BENEFIT CONSIDERATIONS Conceptually, cost-benefit analysis can be applied to disposal of solid wastes with a "de minimus" radioactivity concentration by weighting-costs and benefits of alternate means of disposal. In lieu of any other guidance, the interim value of $1,000 per total body man-rem from Appendix I is used herein. In practice, the limited distribution of discarded bulk solid wastes and the critical pathways for exposure of a. man limit the number of people potentially exposed to those who live

on the disposal site or who eat food grown thereon. Therefore, large population doses will not result from disposal of material with "de minimus" concentrations of radioactivity. Assuming the cost of unrestricted disposal of "de minimus" solid waste is zero, the cost of shallow-land burial of low-level radioactive 3 waste is $6/ft , and the population dose associated with shallow-land burial is zero, then a practical cost-benefit criterion for unrestricted . disposal of solid waste is that any waste having an associated population 4 dose potential of less than 6 man-millirem per cubic foot of waste p- discarded in an unrestricted manner is "de minimus." As an illustration that the individual dose rate criterion is more limiting than the cost-benefit criterion, consider the example of the - 3 disposal of 150 m of spent, powdered resin, approximately the volume generated annually at a large light-water reactor power station. If unrestricted disposal causes more than 6 man-area /ft3 , or about 30 man-rem for disposal of the total volume of the waste, then the alternate, shallow-land burial, would be indicated by ALARA considerations. Since the "de minimus" health protection criterion limits the individual dose < l Ac !

rate to 1 area total body dose per year, about 600 persons, each receiving 1 mram/ year for 50 years would be required to reach the 10mit associated with the cost benefit criterion, 30 man-rem, for disposal of the 150 m 3' of waste. Since all of the limiting pathways require that the exposed individual reside directly on the disposal sites or eat food grown there-on, it is hardly reasonable to expect the population exposure to reach the limit of the cost-benefit criterion.- Hence, the "de minimus" limit $PS based on individual dose will result in a lower limit than one based on ALARA considerations. With such a low individual total body dose rate of one millirem per year or less, any cost-benefit interpretation based on an estimate of population integrated dose equivalent is probably unrealistic. The NCRP and ICRP cautions in regard to the inappropriateness of quantita-tive risk-benefit balancing at such a low dose rate is thus persuasive against the use of such an analysis for decisionmaking in connection . with "da minimus" waste disposal (NC75a, IC73). t t 47

6.0 APPLICATION OF ' DIE GENERIC METHOD The aim of this study has been to develop a method for determining "de minimus" concentrations in homogeneous, bulk solid wastes so that they may be disposed of in the manner of ordinary domestic solid wastes without.any special requirements because of the low radioactivity content. The methodology developed has been applied to land disposal of spent, I powdered resin from PWR secondary systems as an examp1'e. phj Neither initial dispersion by air or water, l ' i.e., incineration or sea g dumping, were considered;-however, the methodology developed can be applied to other materials by considering the nature of the source, feasible disposal scenarios, and environmental pathways to man. 6.1 Application to Secondary Resins As an azample of the application of the method, the expected concentration of each radionuclide adsorbed on spent, powdered resin , from PWR secondary systems has been computed using the PWR GALE code (NRC76) to calculate primary coolant concentrations and the SECONDARY a code (by Nuclear Safety Associates) to calculate activity concentrations i. of the spent resins. The "de minimus" concentrations calculated in Section 4 apply, of course, to this type of waste. By comparing the axpected concentrations to the "de minimus" concentration limits, it is possible to rank the isotopes in order of significance. The sum of the ratios of expected to "de minimus" concentrations of all radionuclides in the waste must not exceed unity if the waste itself is to be "de minimus." This method is also sumnarized in Figure 6-1. l 48

Whether Waste Is "de minimus"

49

The ratios of computed concentrations in spent, powderediresins from a FWR secondary system to "de minimus" concentration limits after 3, 6, and 12 months' decay are shown respectively in Tables 6-1, 6-2, 6-3. It can be seen that after 3 months decay (Table 6-1), only Cs-134 Cs-137, Co-60 and Co-58 exceed the "de minimus" concentration limits; i and after 1 year's decay only Cs-134, Cs-137 and Co-60 are expected to be in excess of the "de minimus" values. Furthermore, they are more than

   '      one or two orders of magnitude more limiting than any other isotope.

If the concentration of other radionuclides can be related to the con-centration of a few indicator n.uclides, then verification of the activity concentration of the indicator nuclides should be adequate to verify that the waste is "de minimus." Based on the calculated mixture of i radionuclides on spent powdered resin, Cs-137 (with 0.662 Mev gamma ray) and Co-60 (with 1.17 and 1.33 Mev gamma rays) can be used as indicators to measure whether this type of waste is "de minimus." With respect to any particular reactor, specific measurements may be needed to ascertain that Co-60 and Cs-137 are critical radionuclides in spent resin. Although Tables 6-1, '6-2, and 6-3 indicate that the calculated g concentrations of cesium and cobalt do not satisfy the "de minimus" criterion for radiation protection, it should be recognized that the calculation of these radionuclides was based on conservative assumptions. In the PWR GALE code (NRC76), it was assumed that the reactor operated with 0.12% failed fuel and that the water leakage rate from the primary to the secondary loop in the reference reactor was 100 pounds / day. In order to achieve the "erpected" concentrations, both of these conditions must occur simultaneously. Most of the time one or both of these param-50

i eters will be very much lower than the assumed values. Consequently, most of the time the secondary resins will have concentrations much below the " expected" values calculated herein and this type of waste can be expected to meet the "de minimus" concentration much of the time. 6.2 Practicability of Haasurement It can be seen from Tables 4-3 and 4-4, particularly the latter, that levels at which nuclides must be measured to demonstrate compliance

  $b l
  ?      ,

with "de minimus" concentrations are in the range of 10-6 Ci/ gram. In

        !                         the case of a specific waste type, such as resins, where it can be demonstrated that only a few radionuclides are important, the number of radionuclides which need be analyzed for can be shown to be small.

Furthermore, in the case of spent, powdered resins from PWR secondary

systems where the critical radionuclides, Co-60 and Cs-137, amit distinct, energetic gamma rays, the analytical requirement is clear. In this example case, the limit of measurement of the critical nuclides by

gamma ray spectrometry is in the order of 0.1 to 1 pCi/g. Both of these

      ;                          nuclides can be measured at the activity concentration necessary to demonstrate compliance with the "de minimus" concentration limits cateulated in this study.
