摘　　要：对于非均匀辐射场的个人剂量监测与评价,国内标准目前尚未给出详细具体的方法。为更准确地进行非均匀辐射场的个人剂量监测与评价,参考美国国家标准并结合国内实际情况,设计开发了一套多剂量计系统,并在某核电站大修期间对其进行了试用。试用结果表明,使用该多剂量计系统可以反映出受照人员身体不同区域的剂量分布情况,并且可以提高有效剂量估算的准确性,同时也有助于提高个人剂量、集体剂量的控制管理水平。The feasibility and detailed methods for personal dose monitoring and assessment in non-uniform radiation fields have not been included in national standards. A multi-dosimetry system was designed and developed to obtain a more accurate personal dose assessment in a non-uniform radiation field. The system＆#39;s design was based on the American standards and incorporated in the Chinese actual environment. The system was tested during a nuclear power plant outage. The test results showed that the different components of the body dose distribution of the exposed personnel can be obtained by using of the multi-dosimetry system, and the accuracy of the effective dose estimation can be improved. It can also help to improve the quality of collective and individual dose control management.
