h the exposure limits of 10 CFR 20 to members of the public (AEC 1975). The BEIR Report (BEIR 1972) concludes that the evi- dence indicates that no other living organisms have been identified that are likely to be significantly more radiosensitive than members of the public. The International Atomic Energy Agency (IAEA 1992) concludes that there is no convincing evidence from scientific literature that chronic radiation dose rates below 1 mGy/day (100 mrad/day) will harm animal or plant populations. Limiting exposure in humans to 1 mSv/yr (100 mrem/day) will lead to dose rates to plants and animals in the same area of less than 1 mGy/day (less than 100 mrad/day). The National Council on Radiation Protection and Measurements (NCRP) also concludes that the 1977 ICRP statement “if man is adequately protected, then other living things are also likely to be sufficiently protected” (NCRP 1991) is appropriate. III. REVIEW PROCEDURES The reviewer should take the following steps: (1) Identify the exposure pathways for the biota not considered in the review in ESRP 5.4.1. NUREG-1555 5.4.4-4 October 1999 (a) Consider the exposure pathways to biota other than members of the public and determine if any of these pathways could be expected to result in estimated doses significantly greater than those evaluated by the reviewer for ESRP 5.4.3. (b) If no such pathways can be identified, end the review and proceed to the “Evaluation Findings” of this ESRP. (2) If exposure pathways for biota other than members of the public are identified for which significantly greater (1 m Gy/day) (100 rad/day) doses could be predicted, then consult with the appropriate reviewers for ESRP 2.4 to determine how the biota at these locations could be affected, and calculate doses to these biota, using models and procedures described in Volume 2, Analytical Models and Calculations, of the BEIR (1972) report. ` If the doses are of approximately the same order of magnitude or less than the dose
