济南微堆退役工作要对微堆内的铍反射层、辐照管、上筒节和控制棒等带放射性物件进行拆除和解体,以及水池瓷砖等低放废物的拆除及去污。按照ALARA原则,对退役工作全过程进行了γ剂量率监测,保证工作人员受照剂量合理可行尽量低。方法是用固定的两个电离室探头对大厅不同位置处经行监测,同时用便携式γ剂量率仪对其他地方监测。表1列出了工作人员在退役过程中 Retirement work of Jinan Micro-Heaps should disassemble and disassemble the radioactive objects such as beryllium reflector, irradiation tube, upper tube joint and control rod in the micro-pile, as well as demolition and decontamination of low-level waste such as pool tiles. According to the principle of ALARA, the whole dose of γ dose rate monitoring was carried out for the retired workers to ensure that the doses of workers were reasonable and feasible as low as possible. The method is to use two fixed ionization chamber probes to monitor the different locations of the lobby and monitor them in other places with a portable gamma dose rate meter.
