Abstract

The invention discloses a method for estimating radiation doses caused by gaseous radionuclides and suggestions for protective measures in off-site consequence evaluation of nuclear facility accidents, and relates to the technical field of off-site consequence evaluation of nuclear facility accidents. This method is the potential dose, expected dose, and the potential dose, expected dose, and measures taken by taking iodine, concealment, evacuation, Calculation method of preventable dose and remaining dose of intervention actions such as evacuation, and realized the calculation of dose received by personnel through different routes in evacuation and evacuation actions and the concentration estimation of key nuclides in reservoirs and milk. It can give information such as potential doses, expected doses, preventable doses and remaining doses of each intervention action, suggested intervention area, orientation, administrative division, population, etc. support.

Description

technical field [0001] The invention relates to the technical field of off-site consequence evaluation of nuclear facility accidents, in particular to a method for estimating radiation doses caused by gaseous radionuclides and protective measures in the off-site consequence evaluation of nuclear facility accidents. Background technique [0002] When nuclear facilities or other nuclear facilities seriously deviate from normal operating conditions or accidents occur, the release of radioactive substances may or has lost proper control and reached an unacceptable level, which will cause serious consequences. Therefore, it is of great strategic significance to prevent, control and analyze the hazards of nuclear facility accidents. [0003] Nuclear Facility Accident Consequence Evaluation System is an evaluation system that integrates regional meteorological data, radioactive pollutant migration mode and consequence evaluation, and is used to estimate, evaluate and display accide...
