新运行实用量研究进展及对场所剂量监测的影响

在辐射防护领域，运行实用量用于估算防护量，是场所剂量监测中的重要量值。随着电离辐射粒子类型和能量范围的扩展，现行运行实用量在估算防护量的过程中出现局限。ICRU第95号报告提出了新的运行实用量体系，在定义方式和模体上与防护量相统一，在更广泛的粒子类型和能量范围中实现了对防护量的更好估算。本文重点关注新运行实用量体系在模体应用、转换系数更新、监测仪器的设计和校准等方面对场所剂量监测的影响。

Research progress on new operational quantities and the effects in area dose monitoring

Operational quantities, which are used to estimate protection quantities in the field of radiation protection, are important in area monitoring. The current operational quantities show certain limitations as the particle types and energy ranges are expanded. The International Commission on Radiation Units and Measurements Report 95 proposed a new system of operational quantities, where the definitions and phantoms of the operational quantities are consistent with the protection quantities, enabling better estimation of the protection quantities over wider ranges of particle types and energies. This paper focuses on the effects of the new recommended operational quantity system in area monitoring from the aspects of phantom application, conversion coefficient updating, and monitor design and calibration.
