ght)/(the concentration in dry soil). The feed-to-organism transfer factor is the ratio of (concentration in fresh tissue)/(daily intake of the radionuclide by the organism). Values of bioaccumulation factors, concentration ratios, and transfer factors can be obtained from the International Atomic Energy Agency (IAEA) documents “Sediment Distribution Coefficients and Concentration Factors for biota in the Marine Environment” (Ref. 69) and “Handbook of Parameter Values for the Prediction of Radionuclide Transfer in Terrestrial and Freshwater Environments” (Ref. 70). The applicant should provide the doses from the liquid and gaseous pathways and the total body nonhuman biota dose from all pathways. Table 5-5 is an example of how to present the data. Table 5-5. Nonhuman Biota Doses for Proposed Reactor(s) Biota Liquid Pathway Dose (mrad/yr) Gaseous Pathway Dose (mrad/yr) Total Body Biota Dose All Pathways (mrad/yr) Fish Invertebrate Algae Muskrat Raccoon Heron Duck Source: [Provide all sources of data] The applicant should then compare the estimated total body dose rates to surrogate biota species that would be produced by releases from the proposed facility to the IAEA guidelines in “Effects of Ionizing Radiation on Plants and Animals at Levels Implied by Current Radiation Protection Standards” (Ref. 71) and the NCRP biota dose guidelines in “Effects of Ionizing Radiation on Aquatic Organisms” (Ref. 72). The results of the analysis should be provided in a table similar to Table 5-6. DG-4026, Page 105 Table 5-6.
