HBRODCM 4-3 Rev. 19
BASES Monitoring Program The radiological environmental monitoring program required by this specification provides representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides that lead to the highest potential radiation exposures of members of the public resulting from the station operation. This monitoring program implementsSection IV.B.2 of Appendix I to 10 CFR Part 50 and thereby supplements the radiological effluent monitoring program by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and the modeling of the environmental exposure pathways. Guidance for this monitoring program is provided by the Radiological Assessment Branch Technical Position on Environmental Monitoring. The initially specified monitoring program will be effective for at least the first three years of commercial operation. Following this period, program changes may be initiated based on operational experience.
The required detection capabilities for environmental sample analyses are tabulated in terms of the lower limits of detection (LLD). The LLDs required by Table 4.1-3 are considered optimum for routine environmental measurements in industrial laboratories. It should be recognized that the LLD is defined as an a priori (before the fact) limit representing the capability of a measurement system and not as a posteriori (after the fact) limit for a particular measurement.
Detailed discussion of the LLD, and other detection limits, can be found in HASL Procedures Manual, HASL 300 (revised annually), Currie, L. A., "Limits for Qualitative Detection and Quantitative Determination Application to Radiochemistry," Anal. Chem. 40, 586-93 (1968), and Hartwell, J.

4.2 Land Use Census - Implementation Applicability Applies to the land use census.
Obiective To define the requirements for the conduct of the land use census.
Specification CONTROLS 4.2.1 A land use census shall be conducted and shall identify the location of the nearest milk animal, the nearest residence and the nearest garden of greater than 500 square feet producing fresh leafy vegetables in each of the 16 meteorological sectors within a distance of five miles.
ACTIONS 4.2.2 With a land use census identifying a location(s) that yields a calculated dose or dose commitment greater than the values currently being calculated in ODCM Specification 3.14.1, identify the new location(s) in the next Annual Radioactive Effluent Release report, pursuant to Technical Specification 5.6.3 4.2.3 With the land use census identifying a location which yields an annual calculated dose or dose commitment of a specific pathway which is 20% greater than that at a current sampling location:
- a. add the new location(s) to the radiological environmental monitoring program within 30 days and,
- b. if desired, delete the sampling location having the lowest calculated dose or dose commitments via the same exposure pathway, excluding the control station location, from the monitoring program after October 31 of the year in which the land use census was conducted, and
- c. identify the new location(s) in the next Annual Radioactive Effluent Release Report, Technical Specification 5.6.3, including a revised figure(s) and table for the ODCM reflecting the new location(s).
HBRODCM 4-12 Rev. 19
BASES Land Use Census This specification is provided to ensure that changes in the use of areas at and beyond the Site Boundary are identified and that modifications to the monitoring program are made if required by the results of the census.
This census satisfies the requirements of Section IV.B.3 of Appendix I to 10 CFR Part 50. Restricting the census to gardens of greater than 500 square feet provides assurance that significant exposure pathways via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26 kg/year) of leafy vegetables assumed in Regulatory Guide 1.109, Revision 1 for consumption by a child. To determine this minimum garden size, the following assumptions were used: 1) that 20% of the garden was used for growing broad leaf vegetation (i.e., similar to lettuce and cabbage), and
- 2) a vegetation yield of 2 kg/square meter.
4.3 Monitoring Program - Sampling Requirement Applicability Applies to the radiological environmental monitoring program.
Objective To ascertain that radiological environmental monitoring samples are collected and analyzed in accordance with the radiological environmental monitoring program.
Specification SURVEILLANCE REQUIREMENTS 4.3.1 The radiological environmental monitoring samples shall be collected pursuant to Table 4.1-1 from the locations defined in the ODCM and shall be analyzed pursuant to the requirements of Tables 4.1-2 and 4.1-3.
HBRODCM 4-13 Rev. 19
4.4 Land Use Census - Surveillance Reauirements Applicability Applies to the land use census.
Objective To ascertain that the land use census is conducted in accordance with the radiological environmental monitoring program.
Specification SURVEILLANCE REQUIREMENTS 4.4.1 The land use census shall be conducted once per 24 months during the growing season, by door-to-door survey, aerial survey, by consulting local agriculture authorities or by broad leaf vegetation sampling of at least three different kinds of vegetation. This sampling may be performed at the site boundary in each of two different direction sectors with the highest predicted D/Qs in lieu of the garden census. Specifications for broad leaf vegetation sampling in Table 4.1-1, Item 4.C shall be followed, including analysis of control samples.
4.5 Analysis and Sample Point Description Table 4.5-1 contains the sample point description, sampling and collection frequency, analysis, and analysis frequency for various exposure pathways in the vicinity of HBR for the Radiological Monitoring Program. Figures 4-1 and 4-2 show the location of the various sampling points.
At the time of initial preparation of this manual, the limiting cow milk location was 1.3 miles in the NE sector. As of the time of submittal of this manual, there is no longer a cow present at this location.
The radiological environmental monitoring program has been altered to reflect this change. However, the X/Q, and D/Q values associated with this location have been retained for future reference.

6.0 COMPLIANCE WITH 40 CFR PART 190 6.1 Requirements For Compliance With 40 CFR Part 190 - Radioactive Effluents From Uranium Fuel Cycle Sources Applicability Applies to radioactive effluents from uranium fuel cycle sources.
Obiective To define the dose limits of 40 CFR 190 for radioactive effluents from uranium fuel cycle sources.
Specifications CON rROLS 6.1.1 The dose commitment to any member of the public, due to releases of licensed materials and radiation, from uranium fuel cycle sources shall be limited to <25 mrem to the total body or any organ except the thyroid, which shall be limited to <75 mrem over 12 consecutive months. This specification is applicable to Robinson Unit 2 only for the area within a five mile radius around the Robinson Plant.
ACTI'ONS 6.1.2 With the calculated doses from the release of the radioactive materials in liquid or gaseous effluents exceeding twice the limits of OCDM Specification 2.4.1 .a, 2.4.1 .b, 3.4.1 .a, 3.4.1.b, 3.5.2.1.a, or 3.5.2.1.b, calculations should be made including direct radiation contributions from the reactor unit and from outside storage tanks to determine whether the above limits of ODCM Specification 6.1.1 have been exceeded. If such is the case, prepare and submit to the Commission within 30 days, pursuant to ODCM Specification 9.3.d, a Special Report that defines the corrective action to be taken to reduce subsequent releases to prevent recurrence of exceeding the above limits and includes the schedule for achieving conformance with the above limits.
HBRODCM 6-1 Rev. 19
This Special Report, as defined in 10 CFR Part 20.2203(a)(4), shall include an analysis that estimates the radiation exposure (dose) to a member of the public from uranium fuel cycle sources, including all effluent pathways and direct radiation, for the calendar year that includes the release(s) covered by this report. It shall also describe levels of radiation and concentrations of radioactive material involved, and the cause of the exposure levels or concentrations. If the estimated dose(s) exceeds the above limits, and if the release condition resulting in violation of 40 CFR Part 190 has not already been corrected, the Special Report shall include a request for a variance in accordance with the provisions of 40 CFR Part 190. Submittal of the report is considered a timely request, and a variance is granted until staff action on the same request is complete.
6.1.3 The provisions of ODCM Specification 8.1 are not applicable.
BASES Compliance with 40 CFR Part 190 - Radioactive Effluents From Uranium Fuel Cycle Sources This specification is provided to meet the dose limitations of 40 CFR Part 1 90 that have been incorporated into 10 CFR Part 20 by 46 FR 18525. The specification requires the preparation and submittal of a Special Report whenever the calculated doses from plant generated radioactive effluents and direct radiation exceed 25 mrems to the total body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrems. It is highly unlikely that the resultant dose to a member of the public will exceed dose limits of 40 CFR Part 190 if the reactor remains within twice the dose design objectives of Appendix I, and if direct radiation doses from the reactor unit and outside storage tanks are kept small. The Special Report will describe a course of action that should result in the limitation of the annual dose to a member of the public to within the 40 CFR part 190 limits. For the purposes of the Special Report, it may be assumed that the dose commitment to the member of the public from other uranium fuel cycle sources is negligible, with the exception that dose contributions from other nuclear fuel cycle facilities at the same site or within a radius of 8 km must be considered. If the dose to any member of the public is estimated to exceed the requirements of 40 CFR Part 190, the Special Report with a request for a variance (provided the release conditions resulting in violation of 40 CFR Part 190 have not already been corrected), in accordance with the provisions of 40 CFR Part 190.11 and 10 CFR Part 20.2203(a)(4), is considered to be a timely request and fulfills the requirements of 40 CFR Part 190 until NRC staff action is completed. The variance only relates to the limits of 40 CFR Part 190, and does not apply in any way to the other requirements for dose limitation of 10 CFR Part 20, as addressed in ODCM Specifications 2.2.1 and 3.2.1. An individual is not considered a member of the public during any period in which he/she is engaged in carrying out any operation that is part of the nuclear fuel cycle.
HBRODCM 6-2 Rev. 19
6.2 TOTAL DOSE (40 CFR 190 CONFORMANCE) 6.2.1 COMPLIANCE WITH 40 CFR 190 Compliance with 40 CFR 190 as prescribed by ODCM Specification 6.1 is to be demonstrated only when one or more of ODCM Specifications 2.4.1 .a, 2.4.1 .b, 3.4.1 .a, 3.4.1 .b, 3.5.2.1 .a, and 3.5.2.1 .b is exceeded by a factor of 2. Once this occurs the Company has 30 days to submit this report in accordance with ODCM Specification 9.3.
6.2.2 CALCULATIONS EVALUATING CONFORMANCE WITH 40 CFR 190 To perform the calculations to evaluate conformance with 40 CFR 190, an effort is made to develop doses that are realistic by removing assumptions that lead to overestimates of dose to a MEMBER OF THE PUBLIC (i.e., calculations for compliance with 10 CFR 50, App.I). To accomplish this the following calculational rules are used:
- 1. Doses to a MEMBER OF THE PUBLIC via the liquid release pathway will be calculated.
- 2. Doses to a MEMBER OF THE PUBLIC due to a milk pathway will be evaluated only as can be shown to exist. Otherwise, doses via this pathway will be estimated as <1 mrem I yr.
- 3. Environmental sampling data which demonstrate that no pathway exists may be used to delete a pathway to man from a calculation.
- 4. To sum numbers represented as "less than" (<), use the value of the largest number in the group.
(i.e. <5 + <1 + <1 + <3 = 5)
- 5. When doses via direct radiation are added to doses via inhalation pathway, they will be calculated for the same distance in the same sector.
- 6. The calculational locations for a MEMBER OF THE PUBLIC will only be at residences or places of employment.
NOTE: Additional assumptions may be used to provide situation-specific parameters, provided they are documented along with their concomitant bases.
HBRODCM 6-3 Rev. 19
6.3 CALCULATIONS OF TOTAL BODY DOSE Estimates will be made for each of the following exposure pathways to the same location by age class. Only those age classes known to exist at a location are considered.
6.3.1 Direct Radiation The component of dose to a MEMBER OF THE PUBLIC due to direct radiation will be determined by:
- 1. Determine the direct radiation dose at the plant boundary in each sector, DB,O
- 2. Extrapolate that dose to the calculational location as follows:
DB,0 (1.49E + 6)
DL, --' (XL,e )2 DL,O = dose at calculational location in sector 0.
1.49E6 = square of mean distance to the site boundary (1220 m).
XL,o = Distance to calculational locations in sector 0 in meters.
6.3.2 Inhalation Dose The inhalation dose will be determined at the calculational locations for each age class at risk according to the methods outlined in Section 3.5 of this manual.
6.3.3 Ingestion Pathway The dose via the ingestion pathway will be calculated at the consumer locations for the consumers at risk. If no milk pathway exits in a sector, the dose via this pathway will be treated as <1 mrem /yr.
6.3.4 Other Uranium Fuel Cycle Sources The dose from other fuel cycle sources will be treated as <1 mrem /yr.
HBRODCM 6-4 Rev. 19
6.4 THYROID DOSE The dose of the thyroid will be calculated for each sector as the sum of inhalation dose and milk ingestion dose (if existing). The calculational methods will be those identified in Section 3.5 of this manual.
6.5 DOSE PROJECTIONS Dose projections are to incorporate planned plant operations such as power reduction or outages for the projected period.
6.6 Radioactive Effluents From Uranium Fuel Cycle Sources-Cumulative Doses Applicability Applies to the determination of cumulative doses from radioactive effluents from uranium fuel cycle sources.
Obiective To ascertain that cumulative doses from radioactive effluents from uranium fuel cycle sources are maintained as low as reasonably achievable and within allowable limits.
Specification SURVEILLANCE REQUIREMENTS 6.6.1 Cumulative dose contributions from liquid and gaseous effluents shall be determined in accordance with ODCM Specifications 2.4.1, 3.4.1, and 3.5.2.1 in accordance with the methodology and parameters in the ODCM. For the purposes of this Surveillance Requirement, it may be assumed that fuel cycle sources are negligible, with the exception that dose contributions from other nuclear fuel cycle facilities at the same site or within a radius of 5 miles must considered. In addition, an individual is not considered a member of the public during any period in which he/she is engaged in carrying out any operation which is part of the nuclear fuel cycle.
6.6.2 Cumulative dose contributions from direct radiation from the reactor units and from radwaste storage tanks shall be determined in accordance with the methodology and parameters in the ODCM. This requirement is applicable only under conditions set forth in ODCM Specification 6.1.2.

APPENDIX A METEOROLOGICAL DISPERSION FACTOR COMPUTATIONS Carolina Power & Light Company (CP&L) engaged the services of Dames & Moore to assess the transport and dispersion of the effluent in the atmosphere as outlined in Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants, NUREG 0133 (USNRC 1978). The methodology for this assessment was based on guidelines presented in Regulatory Guide (RG) 1.111, Revision 1 (USNRC 1977).
The results of the assessment were to provide the relative deposition flux and relative concentrations (undepleted and depleted) based on numerical models acceptable for use in Appendix I evaluations.
Regulatory Guide 1.111 presented three acceptable diffusion models for use in estimating deposition flux and concentrations. These were (1) particle-in-cell model (a variable trajectory model based on the gradient transport theory), (2) puff-advection model (a variable trajectory model based on the statistical approach to diffusion), and (3) the constant mean wind direction model referred to here as the straight-line trajectory Gaussian diffusion model (the most widely used model based on a statistical approach). It was resolved that for operational efficiency, the straight-line described in XOQDOQ Program for the Meteorological Evaluation of Routine Effluent Releases at Nuclear Power Stations (Draft), NUREG 0324 (USNRC September 1977) would be used for generating the required analyses of Appendix I. To provide a more realistic accounting of the variability of wind around the plant site, terrain/recirculation correction factors (TCF) were to be determined from a combined puff-advection/straight-line scheme for a one-year meteorological data base.
Dames & Moore was provided a one-year record of meteorological data from the on-site meteorological program at the H. B. Robinson Steam Electric Plant. These data consisted of all collected parameters at both the 11.03-meter and 62.39-meter tower levels for the year 1977. Dames & Moore computed dispersions and depositions using the model described in the reference. The following tables from the reference provide the basis for the meteorological dilution factor development of the technical specifications for Appendix I and were the source of the X/Q and D/Q values used to show compliance with 10 CFR 20 and 10 CFR 50 for noble gases and radioiodines and particulates.
Tables A-1 through A-6 Relative undepleted concentration, relative depleted concentration, and relative deposition flux estimates for ground level releases for both standard distances and special locations for long-term releases.
HBRODCM A-1 Rev. 19
Tables A-7 through A-9 Relative undepleted concentration, relative depleted concentration, and relative deposition flux estimates for ground level releases for special locations for short-term releases.
The X/Q and D/Q values which are used in Appendix B for showing compliance with 10 CFR 20 and 10 CFR 50 when the HBR Plant vent has been modified such that it qualifies as a mixed mode release were based upon the following tables:
Tables A-1O through A-15 Relative undepleted concentration, relative depleted concentration, and relative deposition flux estimates for elevated release for both standard distances and special locations for long-term releases.
Tables A-16 through A-18 Relative undepleted concentration, relative depleted concentration, and relative deposition flux estimates for mixed mode releases for special locations for short-term releases.
It should be noted that the short-term releases were based upon 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> per year of containment purges.
Future Operation Computations The NRC "XOQDOQ" Program (Revision 1) was obtained and installed on the CP&L computer system. In general, Dames & Moore concluded that the straight-line model is as reasonable a projection of concentrations as the puff-advection model. By inclusion of the terrain correction factors developed by a combination of the puff-advection/straight-line scheme with the results of the XOQDOQ Program, ready evaluation of on-site meteorological data may be made.
For routine meteorological dispersion evaluations, the "XOQDOQ" Program will be run with the appropriate physical plant data, appropriate meteorological information for the standard distances, and special locations of interest without a terrain/recirculation factor. The resulting computations will have applied the TCFs to produce a final atmospheric diffusion estimate for the site. The input to "XOQDOQ" for ground level releases at HBR are presented in Table A-1 9 and for mixed mode releases at HBR in Table A-20.

APPENDIX B DOSE PARAMETERS FOR RADIOIODINES, PARTICULATES, AND TRITIUM This appendix contains the methodology which was used to calculate the dose parameters for radioiodines, particulates, and tritium to show compliance with 10 CFR 20 and Appendix I of 10 CFR 50 for gaseous effluents. These dose parameters, Pi and R1, were calculated using the methodology outlined in NUREG 0133 along with Regulatory Guide 1.109, Revision 1. The following sections provide the specific methodology which was utilized in calculating the P1 and R1 values for the various exposure pathways.
B.1 Calculation of Pa The dose parameter, Pi, contained in the radioiodine and particulates portion of Section 3.3 includes pathway transport parameters of the "i" radionuclide, the receptor's usage of the pathway media, and the dosimetry of the exposure. Pathway usage rates and the internal dosimetry are functions of the receptor's age; however, the youngest age group, the infant, will always receive the maximum dose under the exposure conditions for ODCM Specification 3.2.1 .b. For the infant exposure, separate values of Pi may be calculated for the inhalation pathway which is combined with a W parameter based on (X/Q) and the food (milk) and ground pathway which is combined with a W parameter normally based on (D/Q), except for tritium. The following sections provide in detail the methodology which was used in calculating the Pi values for inclusion into this ODCM.
B.1.1 Inhalation Pathway The evaluation of this pathway consists of estimating the maximum dose to the most critical organ received by an infant through inhalation by:
Pi, = K'(BR)DFAi (B. 1-1) where:
Pi, Dose parameter for radionuclide "i"for the inhalation pathway, mrem/yr per
'ICi/m3; K' = A constant of unit conversion; = 106 pCi/t.Ci; BR = The breathing rate of the infant age group, m3/yr; DFAi = The maximum organ inhalation dose factor for the infant age group for radionuclide "i," mrem/pCi.
HBRODCM B-1 Rev. 19
The age group considered is the infant group. The infant's breathing rate is taken as 1400 m3/yr from Table E-5 of Regulatory Guide 1.109, Revision 1. The inhalation dose factors for the infant, DFAi, are presented in Table E-10 of Regulatory Guide 1.109 in units of mrem/pCi. The total body is considered as an organ in the selection of DFAi.
The incorporation of breathing rate of an infant and the unit conversion factor results in the following equation:
Pi, = 1.4x 109 DFAi (B. 1- 2)
B.1.2 Ground Plane Pathway The dose factor from ground plane pathway is calculated by:
Pio = K'K"DFGi 0 (B. 1- 3) where:
Pi = Dose parameter for radionuclide "i"for the ground plane pathway, mrem/yr per ILCi/sec per m 2; K' = A constant of unit conversion;
= 106 pCi/p.Ci; K# = A constant of unit conversion;
= 8760 hr/yr;
, The radiological decay constant for radionuclide "i," sec-';
t = The exposure period;
= 3.15 x 107 sec (1 year);
DFGI = The ground plane dose conversion factor for radionuclide "i," mrem/hr per pCi/m 2.
HBRODCM B-2 Rev. 19
The deposition rate onto the ground plane results in a ground plane concentration that is assumed to persist over a year with radiological decay--the only operating removal mechanism for each radionuclide. The ground plane dose conversion factors for radionuclide "i," DFGi are presented in Table E-6 of Regulatory Guide 1.109, Revision 1.
Resolution of the units yields:
Pic = 8.76 X1I 9 DFGi (0- xt) (B. 1- 4)
B.1.3 Milk The dose factor from the cow/goat-milk-man pathway is calculated by:
= K'r QF(Uap)Fm DFLie_,, (B. 1- 5)
Yp (Xi + kw) where:
Pim Dose parameter for radionuclide "i" for the cow milk or goat milk pathway, mrem/yr per [Ci/sec per m-2; K' A constant of unit conversion; = 106 pCi/pCi; QF The cow's or goat's consumption rate of feed, kg/day (wet weight);
Uap = The infant's milk consumption rate, liters/yr; yp = The agricultural productivity by unit area, kg/m 2; Fm = The stable element transfer coefficient, pCi/liter per pCi/day; r = Fraction of deposited activity retained on cow's or goat's feed grass; DFL = The maximum organ ingestion dose factor for radionuclide "i," mrem/pCi; i = The radiological decay constant for radionuclide "i,"sec";
HBRODCM B-3 Rev. 19
XW The decay constant for removal of activity on leaf and plant surfaces by weathering, sec";
5.73 x 10V sec1 (corresponding to a 14-day half-life);
tf The transport time from pasture cow or goat to milk to infant, sec.
A fraction of the airborne deposition is captured by the ground plane vegetation cover. The captured material is removed from the vegetation (grass) by both radiological decay and weathering processes.
Various parameters which were utilized to determine the Pi values for the cow and goat milk pathways are provided in Table B-1. Table E-1 of Regulatory Guide 1.109, Revision 1, provides the stable element transfer coefficients, Fm; and Table E-14 of the same regulatory guide provides the ingestion dose factors, DFLi, for the infant's organs. The organ with the maximum value of DFLi was used in the determination of Pi for this pathway. The incorporation of the various constants of Table B-1 into Equation B.1-5 results in the following:
For radioiodines and particulates from cow's milk:
PiM = 2.4Xl010 rFm DFLie_ý"t (B.1-6)
?Ii + XW For radioiodines and particulates from goat's milk pathway:
PiM = 2.8x109 rFm DFL e.,ietf (B. 1 -7)
Xi + Xw The concentration of tritium in milk is based on its airborne concentration rather than the deposition rate and is calculated by:
PrM = K'K" Fm QF Uap DFLT 0.75(0.5/HI) (B. 1- 8) where:
PTM Dose parameter for tritium for the cow milk and goat milk pathways, mrem/yr per i.Ci/m 3 ;
K"# A constant of unit conversion; S 103 gm/kg; H = Absolute humidity of the atmosphere, gm/m 3; HBRODCM B-4 Rev. 19
0.75 = The fraction of total feed that is water; 0.5 The ratio of the specific activity of the feed grass water to the atmospheric water; DFLT Maximum organ ingestion dose factor for tritium, mrem/pCi.
B.2 Calculation of R&Followingq Regulatory Guide 1.109 Methodologqy The radioiodine and particulate ODCM Specification 3.5.2.1 is applicable to the location in the unrestricted area where the combination of existing pathways and receptor age groups indicates that the maximum potential exposure occurs. The inhalation and ground plane exposure pathways shall be considered to exist at all locations. The grass-goat-milk, the grass-cow-milk, grass-cow-meat, and vegetation pathways are considered based on their existence at the various locations. Ri values have been calculated for the adult, teen, child, and infant age groups for the ground plane, cow milk, goat milk, vegetable, and beef ingestion pathways. The methodology which was utilized to calculate these values (see Tables 3.5-1 through 3.5-19) is presented below and follows the guidance given in Regulatory Guide 1.109.
B.2.1 Inhalation Pathway The dose factor from the inhalation pathway is calculated by:
Ri' = K'(BR )a(DFAi),, (B.2 - 1) where:
Ri, = Dose factor for each identified radionuclide "i" of the organ of interest, mrem/yr per pCi/m 3; K' = A constant of unit conversion;
= 106 pCi/plCi; (BR)a = Breathing rate of the receptor of age group a, m3/yr; (DFAi)a = Organ inhalation dose factor for radionuclide "i"for the receptor of age group a, mrem/pCi.

A tabulation of DFGi values is presented in Table E-6 of Regulatory Guide 1.109, Revision 1.
SF = The shielding factor (dimensionless);
A shielding factor of 0.7 is suggested in Table E-1 5 of Regulatory Guide 1.109, Revision 1.
Ii = Factor to account for fractional deposition of radionuclide "i."
For radionuclides other than iodine, the factor Ii is equal to one. For radioiodines, the value of LI may vary. However, a value of 1.0 was used in calculating the R values in Table 3.5-1.

For radionuclides other than iodine, the factor Ii is equal to one. For radioiodines, the value of Ii may vary. However, a value of 1.0 was used in calculating the R values in Tables 3.5-8 through 3.5 15.
Milk cattle and goats are considered to be fed from two potential sources, pasture grass and stored feeds. Following the development in Regulatory Guide 1.109, Revision 1, the value of f, was considered unity in lieu of site-specific information. The value of fp was 0.667 based upon an 8 month grazing period.
Table B-1 contains the appropriate parameter values and their source in Regulatory Guide 1.109, Revision 1.
HBRODCM B-8 Rev. 19
The concentration of tritium in milk is based on the airborne concentration rather than the deposition.
Therefore, the R, is based on X/Q:
RTM = K'K Fm QF U.p (DFLj)a 0.75(0.5/H) (B.2- 4) where:
RTM Dose factor for the cow or goat milk pathway for tritium for the organ of interest, mrem/yr per ,Ci/m 3; K = A constant of unit conversion;

And other parameters and values are given above. A value of H = 8 grams/ meter3 , was used in lieu of site-specific information.

For radionuclides other than iodine, Ii is equal to one. For radioiodines, the value of ri may vary.
However, a value of 1.0 was used in calculating the R values in Tables 3.5-5 through 3.5-7.
All other terms remain the same as defined in Equation B.2-3. Table B-2 contains the values which were used in calculating Ri for the meat pathway.
The concentration of tritium in meat is based on its airborne concentration rather than the deposition.
Therefore, the Ri is based on X/Q.
RTB = KIK"Ff QF Uap (DFLi)a 0.75(0.5/H) (B.2 - 6) where:

B.2.5 Vegqetation Pathway The integrated concentration in vegetation consumed by man follows the expression developed in the derivation of the milk factor. Man is considered to consume two types of vegetation (fresh and stored) that differ only in the time period between harvest and consumption, therefore:

All other factors as defined before.
For radionuclides other than iodine, the factor Ii is equal to one. For radioiodines, the value of Li may vary. However, a value of 1.0 was used in Tables 3.5-2 through 3.5-4.
Table B-3 presents the appropriate parameter values and their source in Regulatory Guide 1.109, Revision 1.
In lieu of site-specific data default values for fL and fg, 1.0 and 0.76, respectively, were used in the calculations on Ri. These values were obtained from Table E-15 of Regulatory Guide 1.109, Revision 1.
The concentration of tritium in vegetation is based on the airborne concentration rather than the deposition. Therefore, the Ri is based on X/Q:
