Abstract
The effects of man's residence time inside building structures on radiation doses from routine releases of radionuclides to the atmosphere were studied using models which were suitable for radiological assessments involving arbitrary source terms. Dose reduction factors from building shielding are calculated for internal exposure from inhaled radionuclides and external photon exposure from airborne and surface-deposited radionuclides. The model for internal dose accounts for air ventilation and the deposition of radionuclides on inside surfaces of the building. External photon dose rates are calculated using the point-kernel integration method. The computer code BUSH is used to implement the models. The results of model-parameter sensitivity studies and an application of the models to a radiological assessment are discussed.Keywords
