The determination of the area affected by relocation after nuclear accidents

摘要

Relocation is one of the protective actions that may be introduced to protect the public following an accidental release of radioactive material into the environment. This paper presents the results of a study on the quantitative prediction of the area affected by relocation after nuclear accidents. In this study, the relationship between the areas affected by relocation and the intervention level for implementing relocation as well as source term has been quantitatively described. All the calculations presented in this paper have been done using the European package for accident consequence assessment COSYMA. To estimate the influence of the assumptions made in the calculations on the general applicability of the results, a sensitivity study has been carried out for source term variations and sampling of weather sequences.
