Pathway analysis concepts for radiological impact assessment

Technical Report:

Abstract

The concepts underlying exposure pathways analysis are outlined with reference to the features of the two broad types of radionuclide transport models now in use - dynamic and steady-state - and the methods for constructing and developing them. By way of illustration, representative radiation doses are estimated for the four main exposure pathways likely to be involved in the land application of effluent water from Retention Pond 2 of Ranger Uranium Mines. These include: external irradiation by {sup 226}Ra and natural uranium (Un at) in soil, ingestion of {sup 226}Ra and Un at in food, inhalation of {sup 222}Rn daughter products from {sup 226}Rn in soil, and inhalation of {sup 226}Ra and Un at in airborne dust resuspended from soil. Consideration has been given to local residents pursuing a traditional lifestyle on conclusion of the land application program. Because of the possible importance of the contribution from resuspended dust, currently available data are explored in refining the methodology for the pathway and developing a more appropriate model for it. 37 refs., 9 tabs., 6 figs.
