介绍了一套远程控制个人剂量率仪的工作原理、结构和特性。在高中子产额的中子发生器实验大厅,用该仪器初步测量了中子活化产生的辐射剂量率。当直流中子产额为2×1011s-1时,停机1h后测得中子活化产生的辐射剂量率为99.9μSv/h;停机39h后辐射剂量率降为24.4μSv/h。当直流中子产额为3.2×1010s-1时,停机36min后测得中子活化产生的辐射剂量率为21.9μSv/h。测量结果可供物理实验人员和中子发生器运行人员参考。
Introduced a set of remote control personal dose rate meter working principle, structure and characteristics. In the experiment hall of neutron generator with high neutron yield, this instrument was used to measure the radiation dose rate of neutron activation. When the DC neutron yield is 2 × 1011 s-1, the radiation dose rate measured by neutron activation is 99.9 μSv / h after 1 h of shutdown and the radiation dose rate is reduced to 24.4 μSv / h after 39 h of shutdown. When DC neutron yield is 3.2 × 1010s-1, the radiation dose rate measured by neutron activation after 36min shutdown is 21.9μSv / h. The measurements are for reference by both physical and neutron generator operators.
