核电站的剂量控制与辐射防护最优化

DOSE CONTROL AND ALARA AT NUCLEAR POWER PLANTS

随着我国核电事业的发展，从一开始就认真做好对核电站的剂量控制和辐射防护最优化的管理、评价和监督工作已经提到议事日程。本文概要介绍了核电站在照射最优化管理方面的两项基本任务，核电站辐射防护最优化管理的基本要素和技术措施。同时指出，最优化管理可以采用定性和定量的两种方法。在定量方法中采用一些量化指标是有益的，但应注意它们的具体含义和应用范围。

With the development of NPPs in China, paying attention to dose control and ALARA at NPPs is very important. This paper briefly introduces two primary tasks for exposure control at NPPs, primary consideration of ALARA and the common technical methods. It points out that adoption of some quantitative indicators is useful, but it is important to bear it in mind that these “Values of dose avoided” are situation specific. (
