| Popis: |
After a large-scale contamination of an urban area with gamma-ray emitting radionuclides (e.g. caesium isotopes) decision makers will need guidance as to its potential radiological consequences and to optimum means of mitigation. To provide such information, a dynamic radioecological model PARATI has been developed and used to simulate the contamination of realistic urban environments in a computer model and to estimate the various radiation fields in such environments. In this study, the computer-simulated realistic behaviour and movements of individuals and populations in such radiation fields are described, and the resulting radiation exposures and their variabilities are estimated. For the scenarios considered, the doses of individuals in the same contaminated environment may vary by more than one order of magnitude. Studies on population habits and on the behaviour of radionuclides on important urban surfaces even a long time after the contamination might reduce the uncertainty considerably. |
