ld Infant Fish and Invertebrate Adult Teen Child Direct Radiation All Source: [Provide all sources of data.] DG-4026, Page 101 Gaseous Effluent Pathway The ER should contain the following: • Gaseous pathway doses to the MEI using the currently NRC-approved computer code (e.g., GASPAR II) (Ref. 66), at the nearest residence, garden, and meat animal and the exclusion area boundary (EAB) that comply with RG 1.109. The input and output files used in the analysis should be provided to the NRC staff for confirmatory review. • The calculated annual collective population doses in units of person-rem for this pathway based on an estimated population distribution late in the timeframe of the proposed license. o The following activities should be considered in the dose calculations: (1) direct radiation from immersion in the gaseous effluent cloud and from particulates deposited on the ground; (2) inhalation of gases and particulates; (3) ingestion of meat and ingestion of milk from animals eating grass affected by gases and particulates deposited on the ground; and (4) ingestion of garden vegetables affected by gases and particulates deposited on the ground. • The gaseous effluent releases used in the estimate of dose to the MEI and population and other parameters used as inputs to the computer program should be provided (e.g., population data, atmospheric dispersion factors, ground deposition factors, receptor locations, and consumption factors). • The doses to the MEI should be presented in a table similar Table 5-2.
