微型中子源反应堆是我院研制的第一座示范性小型中子堆。为进一步推广其应用,搞清在正常工况下的辐射水平,废气和废水中的放射性核素浓度以及对环境的影响是极其重要的。我们采用高压电离室和高灵敏度中子雷姆仪测量了厂区内外γ和中子辐射场。结 Micro-neutron source reactor is the first demonstration of small neutron reactor developed by our hospital. To further promote its use, it is important to understand the level of radiation under normal conditions, the concentration of radionuclides in exhaust gas and wastewater, and the impact on the environment. We measured the γ and neutron radiation fields both inside and outside the plant using high-voltage ionization chambers and high-sensitivity neutron Re meters. Knot
