【摘要】 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。更多还原

【Abstract】 The working principle and the structure and performances of a long distance controllable individual radiation dose ratio instrument are described.The radiation dose ratio produced by neutron activation is elementarily measured by using this instrument in the neutron generator hall with high neutron yield.When neutron yield arrives to 2×1011 s-1,the radiation dose ratio produced by neutron activation is 99.9 μSv/h in 1 h after the generator being stopped.The radiation dose ratio is reduced to 24.4 μSv/h in 39 h after the generator being stopped.When neutron yield is 3.2×1010 s-1,the radiation dose ratio produced by neutron activation is 21.9 μSv/h in 36 min,after the generator being stopped.The measurement results may provide referrence for physical experimenters and neutron generator operators.更多还原
