目的利用场所空气气溶胶浓度对三种不同类型工作场所中工作人员的个人内照射剂量进行估算,为核工业生产企业进行职业健康管理和评价单位进行职业健康评价提供方法依据。方法利用估算公式,结合工作场所空气中放射性气溶胶浓度实测数据,对个人内照射剂量估算过程以及估算公式中的参数应用进行详细、完整的描述和解释。结果能够利用场所空气气溶胶浓度正确估算三种情况下的个人内照射剂量。结论通过正确地估算个人内照射剂量,对工作人员的防护效果进行评价,为职业健康管理提供方法依据。
Objective To estimate the personal internal dose of workers in three different types of workplaces by using the concentration of aerosol in a place, and to provide a method basis for occupational health management of nuclear industrial enterprises and occupational health evaluation. Methods Based on the measured data of radioactive aerosol concentration in the air of the workplace, the estimation formula and the application of the parameters in the estimation formula are described and explained in detail and completely. As a result, it is possible to correctly estimate the intra-personal exposure dose in three cases using the aerosol concentration at the site. Conclusions Evaluating the protective effect of the staff by correctly estimating the internal dose of the individual provides the method basis for occupational health management.
