本工作利用中子周围剂量当量测量仪LB6411、高气压电离室RSS-131和NaI剂量率仪MAR-1561U对中国原子能科学研究院周围展开天然贯穿辐射水平调查。环境辐射中的3种主要成分分别为宇宙射线电离成分、中子成分及天然γ成分。1)中子成分的监测相对独立。测量过程中,借鉴国内外相关工作中采用的技术路线,采用高灵 In this work, we use the LB6411 neutron dosimeter, RSS-131 high pressure ionization chamber and MAR-1561U NaI dosimeter to investigate the natural radiation level around the China Institute of Atomic Energy. The three main components of environmental radiation are the cosmic ray ionization components, neutron components and natural gamma components. 1) The monitoring of neutron components is relatively independent. Measurement process, drawing on the relevant technical work at home and abroad, the use of high spirit
