[目的 ]了解福建省放射工作人员外照射个人剂量水平。 [方法 ]用 Li F( Mg、Cu、P)热释光剂量计连续监测。 [结果 ]1998和 1999年全省放射工作人员的年平均有效剂量当量为1.54和 1.0 3m Sv· a-1;94 .98%的工作人员年有效剂量当量小于 5m Sv;核医学科工作人员年有效剂量当量较高 ,X射线诊断次之 ;年剂量大于 15m Sv的人员占比例较小 ,但对本工种的年集体剂量贡献较大。 [结论 ]福建省大部分放射工作场所、防护设施及工作人员的防护水平是安全的
[Objective] To understand the personal radiation dose level of radiation workers in Fujian Province. [Method] The LiF (Mg, Cu, P) thermoluminescence dosimeter was used for continuous monitoring. [Results] The annual average effective dose equivalent of radiation workers in the whole province was 1.54 and 1.0 3m Sv · a-1 in 1998 and 1999, 94.98% of them were less than 5m Sv per year, and that of nuclear medicine staff The effective dose equivalent is higher, followed by X-ray diagnosis. The annual dose of more than 15m Sv accounted for a small proportion, but the annual collective dose of this species contribute more. [Conclusion] Most of the radiation workplaces in Fujian Province, protective facilities and staff protection level is safe
