四川某大型γ辐照装置的监督性监测结果分析

Supervision Monitoring and Evaluation of a Large-scaleγIrradiation Facility in Sichuan in 2018

为了向监管部门的监管提供可靠的技术依据,按照国家相关技术规范和标准要求对某大型γ辐照装置辐照室四周建筑物内外环境γ辐射剂量率、贮源井水、辐照室外土壤等进行了监督性监测,了解γ辐照装置是否对职业员、公众、周围环境造成影响或影响的程度是否在控制标准内;结果分析表明,大型γ辐照装置在正常平稳运行时,不会对职业人员、公众、周围环境造成放射性影响。对于大型γ辐照装置,监督性监测作为辐射监管的重要手段,应定期进行,及时发现问题并查明原因,防止发生辐射事故。

In order to provide reliable technical basis for the supervision of the regulatory authorities,according to the relevant national technical specifications and standards,the gamma radiation dose rate inside and outside the buildings around the irradiation room of a large-scale gamma irradiation device,reservoir well water,and soil outside the irradiation room were monitored to find out whether the gamma irradiation device has an impact on the staff,the public and the surrounding environment The results show that the large-scale gamma irradiation device will not affect the staff,the public and the surrounding environment in normal and stable operation.As an important means of radiation supervision,supervisory monitoring should be carried out regularly to find out the problems and find out the causes in time to prevent radiation accidents.
