目的了解卷烟机工作场所辐射水平和工作人员受照剂量。方法仪器法和热释光剂量法。结果在卷烟机正常工作状态下,距源表面5 cm、100 cm处泄漏射线均值分别为12.08μSv.h-1和0.34μSv.h-1。工作人员人均年受照剂量为0.836mSv。结论卷烟机工作场所辐射水平和工作人员受照剂量符合国家标准。
Objective To understand the level of radiation in the workplace of the cigarette maker and staff exposure dose. Methods Instrumentation and thermoluminescence dosimetry. Results In the condition of normal operation of cigarette machine, the mean values of leakage radiation at 5 cm and 100 cm from the source surface were 12.08 μSv.h-1 and 0.34 μSv.h-1, respectively. The per capita annual exposure of staff is 0.836mSv. Conclusion Cigarette machine workplace radiation levels and staff exposure dose in line with national standards.
