【 摘 要 】

Method Monte Carlo is applied to assess the radiological impacts to the environment. As such cases, determining the dose rates due to external radiation source is considered, that is induced by radioactive inert gases when they are released from a nuclear power plant; also to estimate the volumetric concentrations of the released radioactive inert gases, and other characteristics associated with the use of gamma detectors of the automated radiation monitoring systems of the environment and unmanned aircraft radiometric system. In order to assure the reliability and the accuracy of the calculations by Monte Carlo method for the dose rates estimations, the results are compared with the results that obtained by the integral method, which showed satisfactory agreement.
