Generic Models for Use in Assessing the Impact of Discharges of Radioactive Substance to the Environment.
IAEA Vienne / Safety Reports Series No. 19 / STI/PUB/1103 (216 pp., 21 figures; 2001)
This Safety Report describes an approach for assessing doses to members of the public as part of an environmental impact analysis of predictive radioactive discharges. This is achieved by using screening models which describe environmental processes in mathematical terms, producing a quantitative result. This report supports Safety Standards Series No. WS-G-2.3, Regulatory Control of Radioactive Discharges to the Environment (2000), and expands on and supersedes Safety Series No. 57, Generic Models and Parameters for Assessing the Environmental Transfer of Radionuclides from Routine Releases (1982).
