4. Q. Have you ever published in the scientific literature dealing with medicine, cancer research, radiation and health?

A. Attached to my testimony is a complete bibliography of my publications. My publications now number in excess p

\)

e o of 200 scientific articles, reports, chapters and

() reviews in the open literature, They are all in the fields of radiological sciences, medicine and surgery, radiobiology, radiation sciences and health, cancer biology, and related disciplines.

5. Q. Briefly describe the BEIR Committee, NCRP, ICRP, the relationship between them and your. personal participation in each committee.

A. The BEIR Committee is a standing expert scientific advisory committee on radiation and health effects of radiation of the National Academy of Sciences - National Research Council, viz., the Committee on the Biological Effects of Ionizing Radiations. The National Council on Radiation Protection and Measurements (NCRP) is an expert scientific advisory committee on radiation and health effects chartered by the U.S. Congress in 1964 (originally dating back to 1929) with designated responsibility to collect, analyze scientific data and develop recommendations about protection against radiation and on radiation measurements, quantities and units. The International Commission on Radiological Protection (ICRP) is the oldest expert scientific i

advisory body on radiation and health; it dates to l

1928. The ICRP is represented by scientists from some 15-20 countries throughout the world with responsibilities O

\j

1 to evaluate the health risks of radiation, particularly

(^)

V -

concerning radioisotopes and medical applications, estimate the extent of these risks, and recommend limits on radiation exposures to worker populations and the general population. These advisory committees on radiation of international and national composition have, for these many years, met and served effectively to discuss, to review, to evaluate, and to report on three important matters of societal concern; (1) to place into perspective the actual and potential harm to the health of man and his descendants in the present and in the future from those societal activities in-volving the use of ionizing radiations; (2) to develop quantitative indices of harm based on dose-response relationships to provide a scientific basis for the evaluation of somatic and genetic risk so as to better protect human populations exposed to low-level radiation; and (3) to identify the sources and levels of radiation which could cause harm, to assess their relative importance, and to provide a framework on how to reduce unnecessary radiation exposure to human populations.

I was a member of the 1972 BEIR I Committee, and on the Subcommittee on Somatic Effects. I was Vice-Chairman of the 1976 BEIR II Committee. I was a member O

of the 1980 BEIR III Ccmmittee, on the Subcommittee

/ on Somatic Effects, and Chairman of the Ad Hoc Committee to Estimate Radiation Cancer Risks on Low-dose, low-LET whole-body Radiation. I am on the ICRP, and a member of Committee 1, which deals with risk estimation and all health effects of exposure to ionizing radiations.

6. Q. What is the scope and purpose of your testimony?

A. The scope and purpose of my testimony is to respond to that portion of Contention 2 of intervenors DAARE and SAFE which are within my scientific and medical expertise. In creating this testimony, I have con-sidered both the specific language of contention 2 and certain supplementary information provided by DAARE and SAFE in response to discovery initiated by Commonwealth Edison Company. Contention 2 generally asserts that the health effects of projected routine release of radioactivity for residents of the DeKalb-Sycamore and Rockford areas should be re-evaluated.

This re-evaluation, it is claimed, should take account of routine releases of radioactivity both from the Byron Station and other nuclear power plants which are owned by Commonwealth Edison Company and are operating now or will be operating in the future.

I

a a Q. Describe the characteristics of ionizing radiation

(]) 7.

which are associated with routine releases of radio-activity from nuclear power plants in the United States.

A. Under normal _ operating conditions the radiation resulting from the routine release of radioactive isotopes (primarily gamma radiation, but beta, alpha, and neutron radiations also exist in very minute amounts) from a nuclear power station is in the order of 1 to 2 per cent of the combined average level of natural background and medical background radiation exposure; this is generally assumed to be negligible.

S. O. What is the definition of low-LET radiation and how does it differ from high-LET radiation?

A. Linear energy transfer (abbr.,LET) is defined as the average amount of energy lost per unit of ionizing particle spur-track length. Low-LET radiation is sparsely ionizing radiation and is characteristic of electrons, x-rays, and gamma rays. Low-LET radiations are those encountered primarily associated with the routine operation of nuclear power plants.

High-LET radiation is characteristic of alpha particles and fast neutrons. These are commonly encountered in the operationt of high energy accelerators.

,, 9. - Q. What are the observed biological effects of low-LET l *

,'" j radiation caused in human beings?

A. Briefly low-LET radiation can affect the cells and tissues of the body in three important ways. First, if the damage caused on the DNA molecule occurs in one or a few cells, such as those of the blood-forming tissues, the irradiated cell can occasionally transform into a cancer cell, and, after a period of time, there is an increased risk of cancer developing in the exposed individual. This biological effect is carcinogenesis; and the health effect, cancer. Second, if the embryo or fetus is exposed during gestation, injury can occur in the proliferating and differentiating cells and tissues, leading to abnormal growth. This biological effect is teratogenesis; and the health effect, develop-mental abnormality in the newborn. Third, if the macro-molecular lesion occurs in the reproductive cell of the testis or the ovary, the hereditary genome of the germ cell can be altered, and the injury can be expressed in the descendants of the exposed individual. This biological effect is mutagenesis; the health effect, genetically related ill-health.

There are a numb 2r of other important biological effects of ionizing radiation, such as induction of cataracts in the lens of the eye or impairment of fertility, but these three important delayed or late p) s, biological effects - carcinogenesis, teratongenesis and mutagenesis - stand out as those of greatest concern.

_9_

10. O. How have these biological effects been observed?

H{}

A. A considerable amount of scientific information is now known from epidemiological studies of exposed human populations and from laboratory animal experiments.

Furthermore, the scientific evidence indicates that any exposure to such delayed or late radiation, even at low levels of dose, carries some risk of such health effects. And as the dose of radiation increases above very low levels, the risk of these delayed or late health effects increases in exposed human populations.

11. .Q. What are the observed health effects of low-LET radiation on human beings?

A. A number of important observations on the late health effects of low-LET radiation have now emerged, about which there is general scientific agreement. These observations are based primarily on evaluation of epidemiological surveys of exposed human populations, on. extensive research in laboratory animals, on analysis of dose-response relationships of carcinogenesis, teratogenesis'and genetic effects, and on known mechanisms of cell and tissue injury in vivo and in vitro. Cancer-induction is considered to be the most important late somatic effect of low-dose, low-LET ionizing radiation.

The different tissues appear to vary greatly in their O) x_

a ,

-ID-relative susceptibility to cancer-inductionby radiation.

O Influences affecting the cancer risk include: age at the time of irradiation, and at the time of the expression of the disease, sex, and radiation factors and types -

LET and relative biological effectiveness - affecting the cancer risk.

Effects of growth and development in the irradiated embryo and fetus have been observed and these effects are related to the gestational stage at which exposure occurs. It appears that a threshold level of radiation dose and dose rate may exist below which gross teratogenic effects will not be observed.

Estimation of the radiation risks of genetically related ill-health are based mainly on laboratory animal observations - primarily from laboratory mouse experiments -

because of the paucity of data on exposed human populations.

Genetic effects due to ionizing radiations have never been directly observed in man. However, they have been observed in laboratory animals. Our knowledge of fundamental mechanisms of radiation injury at the genetic level is far more complete than, for example, of mechanisms of radiation carcinogenesis, thereby permitting greater assurance in extrapolating informa-tion on genetic mutagenesis from laboratory animals to man.

12. Q. At what level of radiation doses have these health k-)g effects been observed?

A. Epidemiological surveys of exposed human populations are highly uncertain in regard to the forms of the dose-response relationships for radiation-induced cancer in man. This is especially the case for low-level' radiation. It has been necessary to estimate human cancer risk from low radiation doses primarily from observations of relatively high doses, frequently greater than 100 rads. While radiation-induced cancer in man has been observed at levels below 50 rads, the epidemiological surveys are too uncertain to provide reliable dose-response data. Surveys of developmental abnormality in the newborn demonstrate teratogenic health effects in the 10-19 rad dose range. Genetic effects in exposed human populations have never been demonstrated even after high-level exposure.

13. Q. Describe the relationship between a rem and a rad.

4 A. A rad is the unit of absorbed dose of radiation =

100 ergs / gram. In the new SI Unit system, 100 rads =

1 Gy. The rem is the unit of dose equivalent (used in radiological protection) = absorbed dose (in rads) times quality factor times distribution factor times any other necessary modifying factors; it represents a quantity of radiation that is equivalent - in (J

~N biologic damage of a specified sort - to 1 rad of 250-kVp x-rays. In the SI system, 100 rems 1 Sv.

14. Q. Uhat is known about the health effects from radiation doses at very low levels -- about 100-150 millirem annually?

A. We do not know what health effects are at dose rates as low as a few hundred millirem per year, that is, a few factors above natural background radiation exposure. It is probable that if any. health effects do occur, they will be masked by environmental or other competing factors that produce similar health effects.

15. Q. .Briefly describe the teratogenic effects of low-level radiation on humans.

A. Developing mammals, including man, are sensitive to radiation during their intrauterine and early postnatal

.-13--

life. The developmental effects of-radiation on U<s the embryo and fetus are related to the stage at which exposure occurs. The existence of a threshold radiation dose below which that effect is not observed may be predicted. There is evidence of such thresholds, but they vary widely, depending on thefabnormality.

Most information comes mainly from laboratory animal studies, but the human data are sufficient to indicate qualitative correspondence for developmentally equiva-lent stages.

-Radiation may produce morphologic abnormalities, general or local growth retardation, or functional im-pairments, if doses are sufficient. Obvious malforma-tions are associated with irradition during the period of major organogenesis, which in man extends approxi-

, mately from the second to the ninth week from conception.

Because the central nervous system is formed during a relatively long period in human development, such abnormalities as microcephaly-and mental retardation figure prominently among the list of radiation effects reported in man.

Atomic-bomb data for Iliroshima show that the fre-quency of small head size was increased by acute air doses in the range of 10-19 rads kerma received during the sensitive period. At Nagasaki, where almost the b

x.)

~. -

entire kerma was due to gamma rays, there was no O increase in the frequency of small head size at air doses below 150 rads kerma, 16 Q.- Briefly describe the genetic effects of low-level radiations on humans.

A. Because radiation-induced transmitted genetic health h

effects have not been demonstrated in man, and because of the likelihood that adequate information will not soon be forthcoming, estimation of genetic risks must be based on laboratory animal data. The genetic dis-orders that can result from radiation exposure are:

(1) those which depend on changes in individual- genes (gene mutations or small deletions); and (2) those which depend on changes in chromosomes, either in total number or in gene arrangement (chromosomal aberrations). Gene mutations are expected to have greater health consequences than chromosomal aberrations.

At low levels of exposure, the effects of radiation in producing either kind of genetic change is proportional to dose. Risk estimates are based either on experi-mental findings at the lowest doses and dose rates for which reliable data have been obtained or on adjustment ~

of the observed data obtained at high doses and dose rates by a dose rate reduction factor. For low doses and dose rates, a linear extrapolation from fractionated-O V

dose and low-dose-rate laboratory mouse data con-0'- tinues to constitute the basis for estimating genetic risk to the general population.

The 1980 DEIR III Report estimates risks of the potential health effects of an average population exposure of 1 rem per 30-year generation. In the first generation, it is estimated that 1 rem of parental exposure throughout the general population would result in an increase of 5-75 additional serious genetic dis-orders per million liveborn offspring. Such an exposure of 1 rem received in each generation is estimated to result, at genetic equilibrium, in an increase of 60-1,000 serious genetic disorders per million liveborn offspring. Within this range of uncertainty, the risk is nevertheless small in relation to current estimates of normally-occurring incidence of serious human disorders of genetic origin --- roughly 11% of liveborn offspring, that is, approximately 107,000 cases per million liveborn.

17. Q. Turning now to the increased risk of carcinogenesis from exposure to low-LET radiation, what are the sources of epidemiological data for the estimation of excess cancer risk in exposed human populations?

A. The chief sources of epidemiological data currently used for risk estimation of radiation-induced cancer in man O

\_J

are the Japanese atomic-bomb survivors exposed to whole-body irradiation in Hiroshima and Nagasaki, the patients with ankylosing spondylitis and other patients who were exposed to partial body irradiation thera-

-peutically, or-to medical diagnostic radiography and flouroscopy, and various occupationally-exposed populations such as uranium miners and radium dial painters.

18. Q. Is a reassessment of the radiation dosimetry previously calculated for the Japanese atomic bomb survivors at Hiroshima and Nagasaki currently under way?

A. Yes. Recent scientific evidence of neutron spectra and radiation attentuation factors for atomic weapons has to a coordinated research effort in order to determine whether the radiation dosimetry data of the Hiroshima and Nagasaki weapons can be estimated on a more accurate basis. Thie reassessment is under way at four large laboratories. Two basic factors are being investigated.

First, since there was no dosimetry present at Hiroshima or flagasaki, the quantities of radiation received at various points within those cities was reconstructed on the basis of tests conducted at the Nevada atomic weapon test site after World War II. The difference in neutron spectra of the weapons actually exploded over Hiroshima and Nagasaki and those exploded at the Nevada test site were not taken fully into account. These O

rx differences'-in neutron spectra yopA4 AAter the V

calculated doses of the high-LET component of the radiation received by the exposed populations of Hiroshima and Nagasaki. This may be of greatest significance for the Hiroshima population since the bomb exploded over Hiroshima had a significant neutron component. The second factor is that the original dosimetry data did not take into account completely the shielding which occurred with respect to the exposed population. This shielding was of two kinds: structural shielding as a result of individuals being protected from radiation by building structures; and tissue shielding, whereby.the doses to a particular organ or tissue were reduced as a result of the location of the organ or tissue in the body.

19. Q. When is this re-evaluation of the Hiroshima and Nagasaki data expected to be complete?

A. About 2 years from now.

20. Q. Does this on-going re-assessment effort cause you to alter any of the conclusions expressed in response to these questions?

A. No. There is now no way of knowing with certainty I

u

, , the magnitude of the change in risk estimates which i O s/

will result from the re-assessment of the Hiroshima and Nagaski dosimetry data. It is possible, however, that such rish. estimates may increase by 10% to 100%.

At levels of exposure to radiation such as those involved in the routine operation of nuclear power plants in Northern Illinois which is the subject of my testimony such an increase would have no effect on the risk to the population in the DeKalb-Sycamore and Rockford areas which I have calculated. Moreover, I should also point out that the other epidemiological data on which my conclusions are based, such as those from patients with ankylosing spondylitis, will not be altered as a result of the re-assessment of the Hiroshima and Nagaski dosimetry data.

21. Q.- Are the health effects of exposure to low-LET radiation such as cancer-induction, characteristically plotted as a radiation dose-response curve?

A. Yes. In recent years, a general scientific hypothesis for estimation'of excess cancer risk in irradiated human l populations, based on theoretical considerations, extensive laboratory animal studies, and limited epidemiological surveys, requires definition of the dose-response relationships between radiation dose and observed cancer incidence. Among the most widely considered dose-response models for cancer-induction

(N by radiation, based on available information and con-V sistent with both scientific knowledge and biophysical and mathematical theory, is one that takes a complex no-threshold linear-quadratic dose-response form.

22.Q. What are the various postulated dose-response curves for radiation doses below 5 rem (or 5 rads of low-LET radiation) and what is the basis for- each such dose-response curve?

A. The no-threshold multicomponent linear-quadratic dose-response curve contains: (1) initial upward - curving linear and quadratic functions of dose, which represent the process of cancer-induction by radiation; and (2) a modifying exponential function of dose, which is generally considered to represent the competing effects I

of biochemical and molecular processes at the sub-cellular level, leading to cell-killing at high doses.

Analysis of a number of dose-incidence curves for

. cancer-induction in irradiated populations, both in humans and in animals, has demonstrated that for dif-ferent radiation-induced cancers different forms of the

! same multicomponent dose-response curve can be-defined.

l Simplifications of the complex model can occur by reducing the number of components which have the least effect on the form of the dose-response relationship in the low-dose range, such simpler models, with increasing

_ complexity, include the linear, the pure quadratic, V

the quadratic (with a linear term in the low-dose region) ,

k/ and finally, the multicomponent linear-quadratic dose-response form with a linear term and with an exponential modifier.

A fourth model, one with a rapidly rising curvilinear dose-response form and a decreasing quadraticfunction (sometimes referred to as " supra-linear" dose-response curve) has also been described; at present it is not used for risk estimation.

23.0 Is 5 rem commonly used as a cut-off in characterizing annual doses as " low" or "small" and, if so, please describe the basis for that characterization?

A. There is no precise definition of low-level (or low-dose) exposure. Scientists would generally agree that low-level radiation is that which falls within the dose range considered permissible for occupational exposure.

According to accepted standards, 5 rem per year to the whole body would be an allowable upper limit of low-level radiation dose for the individual radiation workers.

The NCRP in its Report No. 64 arbitrarily defined " low"

doses of sparsely ionizing (low-LET) radiation as 0-20 rads. (NCRP, report No. 64, 1980, p. 1).
24. Q. Prior to 1980, what was the position of the BEIR com-

! mittee regarding the shape of the dose-response curve i

i for radiation doses below 5 rem?

A. The 1972 BEIR-I Committee and the 1976 BEIR-II Committee

("A

'- considered it scientifically appropriate to adopt a linear no threshold hypothesis of the dose-response to

e p estimate the cancer risk at very low-level radiation

() exoosure where no human epidemiological data are available. -It was assumed the same proportional risks ,

are present at low levels as at high levels of radiation.

25 Q. Has that position of the BEIR Committee regarding the shape of the dose-response curve for cancer-induction changed?

A. Yes. The F.jority of the members of the 1980 BEIR-III Committee chose to adopt as a working model for low-dose, low-LET whole body radiation and carcinogenesis the no-threshold linear-quadratic (i.e., a quadratic function with a linear term in the low-dose region) dose-response form with an exponential term to account for the-observed turndown of the curve in the high-dose region.

However, in applying this multicomponent model, only certain of its derivatives, including the linear, the linear-quadratic, (i . e . , the quadratic with linear term),

and the pure quadratic functions, could prove practical for purposes of estimation of cancer risk. To estimate the carcinogenic risk of low-dose, low-LET, whole-body radiation, the linear-quadratic dose-response curve was considered most appropriate.

3 (v

(~ , 26. Q. Please describe briefly the change in the shape of

'wj' the dose-response curve adopted by the BEIR Committee in 1980 and the circumstances leading up to that change.

A. The Committee's very important task was to estimate the carcinogenic risk of low-dose, low-LET, whole-body radiation. Emphasis was placed almost entirely on the limited number of human epidemiological studies, since it was felt by the majority of the committee members that little information from laboratory animal and from biophysical studies could be applied directly to man. Some scientists of the 1980 BEIR-III Committee considered it necessary to adopt a linear hypothesis of dose-response to estimate the cancer risk at very low-level radiation exposure where no human epidemiological data was available. It is assumed the same proportional risks are present at low levels as at high levels of radiation. Other scientists on the Committee did not accept this position. When there is no human epidemio-logical evidence at low doses of low-LET radiation, these scientists preferred to assume that the risks of causing cancer are proportionally lower, on the basis of the availabic epidemiological surveys, experimental animal and cell-culture evidence and current microdosimetric theory.

Therefore, the 1980 BEIR-III Committee could reasonably adopt as the basis for its consideration of dose-response (y

1'<j 3

F models the quadratic form with a linear term in the rh T) m low-dose region, and with an exponential term for a negative slope in the high-dose region,.i.e., the linear-quadratic dose-response'model. Modifications of the linear-quadratic form were assumed with the linear and quadratic components to be dissimilar or equivalent at some dose - which was consistent with the epidemiological data and the radiological evidence -

and avoided dependence on either of the two extreme forms.

27 Q. From that dose-response curve is it possible to postulate the excess cancer deaths that will occur as a result of a population being exposed to any increment of low-LET radiation?

A. Yes. It would require information on the size of the population at risk, minimal latent periods, magnitude of the effect, duration of the effect, and other parameters of risk (e.g. dose coefficients) and the computational program.

28 Q. Have you made such a postulation of excess cancer deaths for the continuous exposure of a population of 1 million persons to 1 rad per year of additional radiation ex-pressed in ter,ms of excess cancer mortality?

A. Yes. The 1980 BEIR-III Committee used this population and annual dose-rate for one of its illustrative models for estimation of excess cancer risk of low-dose, low-LET, whole-body exposure.

29 Q. What are the results?

A. For continuous lifetime exposure to 1 rad per year, the increase in cancer mortality, according to the linear-quadratic model, ranges from about 3% to 8%

over the normal expectation, depending on the risk projection model (table).

% of normal 2.8 7.7 O)

\.

. 30. Q. Describe the difference between an absolute-risk

( and relative-risk projection models.

A. The absolute risk projection model is the expression of excess risk due to exposure as the arithmetic difference between the risk among those exposed and that obtaining in the absence of exposure. It is ex-pressed as the number of excess cases per million persons exposed per unit dose.

The relative risk projection model is the ex-pression of risk due to exposure as the ratio of the risk among those exposed to that obtaining in the absence of exposure. It is expressed as a ratio or as a percentage.

1 j

3L Q. In your opinion, which of these two risk projection models is a more accurate representation of excess mortality?

A. It is not known whether the cancer risk from radiation would have an absolute or additive effect, or a relative l

or multiplicative effect on the spontaneous cancer rate.

l This is because the mechanisms of carcinogenesis remain l

l poorly understood. It is reasonable to estimate excess cancer risk in both absolute terms and in relative terms. The relative risk approach assumes that the excess cancer risk increases gradually and continuously, l

i and proportional to the spontaneous cancer risk, which

increases with age for nearly all cancers. The O absolute risk approach assumes a constant number of additional cancers throughout life. In my opinion, the relative risk projection mcdel would be more appropriate for estimation of excess cancer risk.

32. Q. Can this statistical projection of excess mortality ever be verified by an epidemiological study of an exposed population?

A. If it is a dose-rate of continuous exposure to 1 rad / year for an entire lifetime, it might be possible to verify this excess provided the population sample size was very largo, the dosimetry was precise, all confounding factors were controlled, and lifestyle factors were carefully considered. However, the chances that this would all exist in a massive epi-demiological survey are highly unlikely. Therefore, from a practical standpoint, it is probable that it cannot be verified by a very large epidemiological study.

33,. Q. Why not?

A. It is not yet possible to make precise low-dose estimates for cancer-induction by radiation because the level of risk is so low that it could not be observed directly in man. There is great uncertainty as to the dose-response

7s functior. most appropriate for extrapolating to the d low-dose region. In studies of exposed animal and human populations, the shape of the dose-response re-lationships for cancer-induction at low doses may be practically impossible to ascertain statistically. This is because the population sample sizes required to estimate or test a small absolute cancer excess are extremely large. Specifically, the required sample sizes are approximately inversely proportional to radiation dose, and if 1,000 exposed and 1,000 control persons are required in each group to test this cancer excess adequately at 100 rads, then about 100,000 in each population group are required at 10 rads, and about 10,000,000 in each group are required at 1 rad.

Thus, it appears that experimental evidence and theo-retical considerations are much more likely than empirical epidemiological data to guide the choice of a dose-response function for risk estimation of cancer induction in human populations.

34. Q. Are you familiar with the testimony of Gerald Lahti in i

this proceeding?

A. Yes.

35. Q. What does Mr. Lahti's testimony state is the annual

)

average radiation dose from the Byron Station and other nuclear power plants?

A. He now calculates an annual' average dose-rate of 0.08 mrem per year.

36. Q. What would be.the postulated health effect response at these dose levels, assuming a population of about 100,000 in the DeKalb-Sycamore and Rockford areas?

A. If one assumes the most conservative estimates of exposure of the population, that each person in the population would receive the maximum dose, and there was no repair of radiation injury in the cells and tissues of the body, then the average individual in the population would receive 5.9 mrem lifetime whole-body dose, the average fetus would receive about 0.03 mrem whole-body dose, and assuming a 30-year generation time the average dose to the testes and ovaries of the population would be about 2.4 mrem.

Normally, 16,700 persons in the 100,000 population would be expected to die of cancer in this population in the absence of any additional radiation exposure above natural background. For continuous lifetime exposure to 0.08 mrem per year above background levels, the increase in cancer mortality, based on the most p

x_J

j s conservative no-threshold, linear dose-response model l would be estimated to be about'0,05 to'0,15 excess cases over the normal lifespan expectation, depending on the risk projection model. This is a statistical value, and in fact the value is negligible. Based on this information, we can conclude, therefore, that there will be no additional cancer cases resulting from the radiation dose levels of 0.08 mrem / year in the population of 100,000 persons living in the DeKalb-Sycamore and Rockford areas.

In this population, the estimated average individual radiation dose to the fetus of pregnant women' exposed to the above annual dose-rate would be below any threshold dose level known to cause any detectable cases of developmental abnormality in the human embryo and fetus, or in laboratory animal experiments. We can conclude that no case of developmental abnormality can be ex-pected to occur in a newborn child as a result of

, radiation exposure of a pregnant woman from the normal operation of the Byron Station and other nuclear power plants.

We would normally expect about 150 cases of genetically-related ill-health among the approximately 1,400 live-born children in a population of-100,000 people. Under the most conservative estimates, from an additional radiation dose of 0.08 mrem / year above

7, natural background radiation we would expect about 0.00001 to 0.0002 additional radiation-induced cases of genetically-related ill-health in all future generations. These represent average numbers, and are miniscule representing less than 1 case in 10 million live births. This number of additional cases is so small that it can never be detected or dis-tinguished, if it does occur, among the cases of naturally occurring genetically-related ill-health.

We can conclude that there will be no detectable cases of genetically-related ill-health resulting from the annual dose-levels calculated above from the Byron Station and other nuclear power plants.

37. Q. Do you expect the health effects you have calculated to actually occur?

A. No. From the above calculations, using even the most conservative dose estimates and dose-response models, I conclude there will be no detectable excess cases of cancer, developmental abnormality in the newborn, or genetically-related ill-health in the population of about 100,000 in the DeKalb-Sycamore and Rockford areas from the airborne radioactive emissions from the Byron Station and other nuclear, power plants during normal operation.

CN V

r'T 38. Q. What are the calculated radiation doses for the V

j population in the DcKalb-Sycamore and Rockford areas, assuming that the TMI accident had occurred

! at the. Byron sitc?

A. Assuming the identical nuclear power plant accident that occurred at Three Mile Island occurred at Byron Station and that the radiation released was identical, then the collective dose to the expcsed population would be estimated to be about 100 person-rem. The average dose to any individual in the population of 100,000 living within 50 miles of the nuclear reactor plant, would be estimated to be about 1 mrem.

39. Q. What would be the postulated health effect response at these dose levels?

A. The conclusions of the President's Commission on the Accident at firee Mile Island, af ter examining all the scientific evidence, were as follows: (1) Since the total amount of radioactivity released during the. nuclear reactor accident was so small, and the total population exposed so limited, that there may be no additional detectable cancers resulting from the radiation from the accident at Three Mile Island. (2) For the same reasons, it is probable there will be no detectable cases of genetically-related ill-health resulting

, from the radiation exposure to the general population

from the accident at Three Mile Island. (3) That O no case of developmental abnormality can be expected to occur in a newborn child as a result of radiation exposure of a pregnant woman from the accident at Three Mile Island.

40. Q. Please describe the manner in which a whole-body dose of low-LET radiation is calculated.

A. There are a number of methods, depending on whether the radiation is external penetrating radiation or internal-emitting radioisotopes in the body. The external penetrating low-LET radiations, such as x-rays and gamma rays, penetrate all or most of the tissues and organs of the body as in the case of exposure to the atomic bombs or x-ray exposure of the fetus in utero.

An average is then estimated, as for example, a midplane dose. Radioisotopes emitting low-LET radiation within the body irradiate the tissues and organs in which they occur, and at distant sites as well. Whole-body dose estimates are determined by multicompartment mathematical models such as those developed by the ICRP which are depende on a number of physical factors and biological factors, including intake, uptake, transport, metabolism, retention, and elimination from the body. The models result in an average whole-body dose estimate, but the individual m

, tissues and organs may have widely differing absorbed

(): doses. When I have referred to whole-body doses of low-LET radiation in this testimony, I have been 1 referring to doses calculated by use of these models. I

41. Q. How are doses of low-LET radiation to individual human organs, such as the thyroid, the pancreas, the liver and the skin calculated?

A. If the radiation is external penetrating x-rays or gamma rays, there are known values of radiant energy deposited in the organs and tissues depending on physical factors, such as the energy absorbed, its distribution, the linear energy transfer, the rate, and the energy spectrum; and on biological factors, such as depth of penetration in the tissues. These calculated values based on mathe-matical and physical models are reasonably precise. If the radiation is from internal emitters, i.e., radio-isotopes within the body, the calculation of internal exposure is much more complex and depends on the physical characteristics of the radioisotope, the energy absorbed by the tissue or organ, and the energy escaping from the organ, and will depend upon the type of radiation emitted, the size and shape of the organ and body of the individual, and the distribution of the radioisotope within the organ or body. There is a great

deal of variation in these physical and biological O- characteristics so th:4t many assumptions and models are used. The numerous possible situations are so varied, and the accuracy of the information available so im-precise that only very simplified mathematical models and calculational techniques are justified. Generally, physicists assume that the organ is ho mgeneous, both in composition and density, and that the radioisotope is distributed uniformly within the organ. The resulting calculation of the total dose to any organ or to the whole body results in imprecice dose estimates.

42. O. Is the calculated whole-body dose the sum of the doses to the individual organs?

A. No. For pentrating external radiations, such as x-rays and gamma rays, the whole-body absorbed dose and the individual organ or tissue absorbed dose may be the same or very different. If the whole body is irradiated, then the absorbed dose to the individual organs would be the same, and would be measured, for example, in rads (i.e., ergs / gram tissue). If one organ receives a high dose, the scatter radiation to the whole body may be very much less. For internal-emitters, i.e., radioisotopes within the body, the distribution of the radionuclide in the body is often quite inhomogeneous and involves geo-metrical complications. For determining whole-body px

\/

absorbed dose, it is usually calculated on a tx l-) uniform distribution and the estimation of average doses reflect the fact that often the actual distribution 4

of-the radioisotope is not accurately known, and thus a detailed distribution of dose within an organ is not

~

known. It follows, therefore, that the whole-body dose'cannot be calculated simply by adding up the inaccurately known inhomogeneous distribution of dose in the organs and tissues. Numerous physical, bio-logical, and chemical factors and assumptions are involved in the calculation of whole-body absorbed dose.

43. Q. Why is that not an appropriate method for calculating whole-body doses from radiation for estimation of total cancer risk?

A. For external penetrating radiation, the dose to the tissues and organs as well as the whole-body is defined as the amount of energy deposited per unit mass.

Therefore, under the most ideal or theoretical con-ditions, the whole-body dose would be the average dose to all the tissues and organs, assuming a large beam irradiating the whole-body. However, the actual dose is usually assumed to be a calculated approxima-tation of dose in the tissues of the body at a particular defined depth, e.g. a geometric construct, such as a sphere of 30 cm diameter, of tissue-equivalent

() mass.

136-For internal radioisotopes in the body, there are difficulties arising due to unknown factors such as distribution of dose, and weighting factors are used in calculating the individual organ doses, in-cluding volume and mass of tissue. The whole-body dose would not be equal to the sum of doses, but rather a weighted average of the organ and tissue doses, and even then would be only an approximation unless all these factors were taken into account.

Therefore, the ICRP has developed mathematical models and geometrical constructs to take into account some of these factors, then has assigned arbitrary weighting risk factors in order to calculate cancer-risks. However, because of the complexity of each individual method of calculation, and the factors that must be taken into account, it is not an appropriate

, method to obtain a whole-body dose from the sum of individual doses to organs and tissues for estimation of total cancer risk, v

Now I'm taking the NRC figure and sort of 7

Q At any rate , let me see if I can sum up for'my own purposes what you are saying.

If, for example, Commonwealth Edison were able to demonstrate that the cumulative dose to the population at 11 4 issue here was 5 millirem or less, would you deem that 12 acceptable as a health physicist?

A I have trouble with your question, because you g

are referring to 5 millirems per year to the total body.

I would want to know what the dose is to any organ, whether 16 that is the maximum dose to any organ. I'd want to know how much you are allowing to the thyroid. I'd want to know gg how you arrived at this value. I'd want to know -- I'd 39 have no problem with your noble gases and what you assume 20 but in meteorology and the passing of clouds and so on, 21 I would want to see very carefully what assumptions you made 22 i

dose.

2 O; Since it's a PWR, I'd be very much interested in Ii 3

the tritium dose. As you know, new -- I call them shims ,

4 like they use in an airplane, where you put in something 1

with a large cross section to sort of even out your reactivity and you produce a lot of tritium this way.

So that some of the PWRs . are putting out much 8

more tritium than the BWRs. The BWRs in general have much 9

3, more noble gases. So I'd take a hard'look at the tritium and how you made the calculational dose.

g There I think I would want to consult with Ted I

Radford who looked into this very carefully in the wind g

scale hearings. There he came up with some problems-I g

hadn't thought very much about. The incorporation of g

tritium in the developing embryo and things of that sort.

But if what you meant by dose in your calculation depended only on the noble gases, I don't think I'd be' 18 very much worried about the 5 millirems per year. If it g

wr m stly from cesium, from the cesium isotopes, I'd 20 be more concerned, because I'd know some of the other 21 g

Then I'd want to check on sone of those others to see what you assumed there.

_Q But in general -- I'm.trying to understand {

4 what you are saying in terms of this 5 millirem dose rate --

6 A In general, as I said before, I favor nuclear power. I think we have to choose some number rather than 8

I zero; on a worldwide population, it means a loss of some 4

lives. Release of this noble gas primarily, and tritium.

The noble gas is worse-than the tritium, I think .

11 But in everything we do, there are some costs 12 for the benefits. I might change my mind af ter thinking g

more about it, but at the' moment I don't believe I would be considerably worried about a total body dose of noble .

gases of 5 millirems p.;r year. I'd hope that this was the maximum, and that you would not on occasions go above that.

DAARE/ SAFE CONTENTION 2 (A)

CONTENTION 2(A)

Due to the concentration of nuclear power plants already in Northern Illinois; the Applicant's record of incidents and violations in existing plants which have emerged since the granting of a Construction License for Byron; and the credibility which must now be given to large scale accident scenarios since TMI, Intervenors contend that the addition of Byron Station operations places an undue and unfair burden of risk from exposure to radioactive materials from accidental releases on DeKalb-Sycamore and Rockford area residents. With the addition of two more nuclear power units in operation at Byron, the potential for cumulative dose effects from discrete accident events at plants in Northern

. Illinois under unfavoraale meteorological conditions poses an unreasonable level of risk to the health and safety of DeKalb-Sycamore and Rockford area residents.

MATERIAL FACTS TO WHICH THERE IS NO GENUINE ISSUE TO BE HEARD

1. The risk (i.e., chance or likelihood of loss or damage) from an accident at an nuclear power nlant decreases rapidly with distance from the plant. (Klopp Testimony, 3 p. 2.)
2. The nuclear power plants in Northern Illinois, other than the Byron Station, are between forty-five (45) and eighty-seven (87) miles from the DeKalb-Sycamore and Rockford areas. (Klopp Testimony, p. 2-3.)
3. The Applicant's existing and nuclear power plants under construction, other than the Byron plant, pose an insignificant incremental risk to the public in the Rockford and DeKalb-Sycamore areas. (Klopp Testimony,
p. 3.)

5 <

4. There are no factors in the design or siting of the

('N Byron Station which poses any unusual or unique risk to

(_j the residents of the Rockford and DeKalb-Sycamore areas. (Klopp Testimony, p. 3.)

DISCUSSION Contention 2(A) raises no factual matters whatsoever.

The location of the nuclear reactors in Northern Illinois is not in dispute. DAARE and SAFE have simply argued that as l a matter of policy this Board should refuse to permit the operation of the Byron Station at a site previously approved by the NRC due to a very slight, indeed insignificant, risk posed to residents in the area from other plants at a con-siderably greater distance from the area. The undisputed facts listed above and reflected in the attached affidavits demonstrate that Applicant is entitled as a matter of law to a favorable decision on Contention 2(A).
