重点放射性污染源监督监测工作的探讨

Investigation on Supervising and Monitoring of Major Radioactive Pollution Source

目的 优化对重点放射性企业监督性监测方案。方法 通过对几个重点放射性污染企业周边大气、水、土壤、生物样品放射性污染因子的监测分析 ,计算出 0～ 1km和 1～ 2km范围公众剂量。结果 企业的污染范围一般在 0～ 1.5km范围内。结论 今后对放射性污染企业进行常规监督性监测 ,只要在 2km范围内进行布点监控 ,可减少不必要的工作量。

Objective In order to optimize the supervisory monitoring proposal of the major radioactive enterprises. Methods We have worked out the public doses within the range of 0～1 km as well as 1～2 km through monitoring analysis of the radioactive pollutant enterprises on the samples of its surrounding air, water, soil and organism. Results Generally the pollutant range of the enterprises runs from 0 to 1.5 km. Conclusion Unnecessary working hours can be shortened as long as we keep the routine supervisory monitor of pollutant enterprises within the range of 2km.
