ansmitted from the proposed plant to living organisms. Figure 5-1 identifies the exposure pathways to humans and Figure 5-2 addresses the exposure pathways to nonhuman biota. • The sources of direct radiation exposures. These sources should include, but not be limited to, independent spent-fuel storage installations, radioactive waste handling facilities, low-level waste storage facilities, condensate storage tanks, fuel buildings, turbine buildings, and skyshine. • The pathways for gaseous effluents considering immersion in the gaseous plume, inhalation of iodines and particulates, ingestion of iodines and particulates through the milk cow, milk goat, meat animal and vegetation pathways, radiation from iodines and particulates deposited on the ground. • The pathways for liquid effluents considering drinking water, ingestion of fish and invertebrates and shoreline activities for water containing radioactive effluents. • Site-specific unusual pathways uniquely associated with the proposed facilities. 5.9.2 Radiation Doses to Members of the Public In the ER, the applicant should provide an estimate of the maximum annual individual dose and the annual total collective doses to the population within 50-mi (80-km) from radioactive gaseous and liquid effluents released from the plant during operation. The ER should provide the inputs for these calculations as well as the source of the data used. The information in the ER should be consistent with the information in the FSAR.
