目的了解南海石油测井放射工作人员外照射个人剂量水平。方法使用Z或IZ鉴别式个人剂量计对南海石油测井放射工作人员进行外照射个人剂量监测。结果 2004～2009年共监测551人,Hp(10)、Hp(3)和Hp(0.07)的人均年受照剂量均为0.63 mSv,实测集体剂量当量分别为346.51人.mSv、347.80人.mSv和348.11人.mSv,南海石油测井放射工作人员的受照年剂量均小于5 mSv。结论南海石油测井放射工作人员受照剂量水平较低,远低于放射工作人员的年受照剂量调查水平。
Objective To understand the individual dose level of external beam radiation of the South China Sea oil well logging workers. Methods A personal oro-dose meter was used to monitor the personal radiation exposure of oil well logging staff in the South China Sea using the Z or IZ discriminant personal dosimeter. Results A total of 551 individuals were monitored from 2004 to 2009, and the annual average dose of Hp (10), Hp (3) and Hp (0.07) was 0.63 mSv. The measured dose efficiencies were 346.51 mSv and 347.80 mSv respectively And 348.11 people.MSv, the South China Sea oil well logging radiation doses were less than 5 mSv. Conclusions The radiation dose of the staff in the South China Sea for oil well logging is relatively low, much lower than the annual survey of radiation workers.
