主 题:radiation dose concrete impurity activation analysis
摘 要:The content analysis of radioactive waste and radiation dose evaluation is considered as one of the important factors in the reactor facility *** kind of buildings consists of the concrete for the most part and uses it as the structure and shield of the ***,the concrete has impurities such as cobalt,europium,nickel,and cesium with specific content depending on the production method or manufacturing *** radioactive nuclides generated from the fundamental components of concrete are considered that it is less contributed to the radiation dose because they are beta decay nuclides in ***,impurities of irradiated concrete in the reactor facilities,are considered occasionally an important evaluation factor for induced *** this study,the influence on the activation of impurities in concrete was evaluated from the radiation dose and induced activity *** calculation was evaluated at the bio-shield which is one of the areas with the highest neutron irradiation among the concrete structure in the reactor *** results show that radioactive nuclides with gamma decay were produced in these ***,the radiation dose of concrete with impurities was higher than concrete without *** increased radiation dose was quantified through the content of impurities.
