摘要: 核电厂事故情况下,气载放射性物质沉积导致的地面照射剂量是场外公众辐射剂量的重要组成部分。本文选取90Sr、137Cs和239Pu等核素,结合其物理去除作用以及再悬浮过程,分析了核电厂事故后地面照射中沉积外照射和再悬浮吸入内照射所致的公众辐射剂量随时间的变化规律。

Abstract: Airborne radionuclides released from nuclear power plant after accidents can be deposited on the ground. Ground exposures can become an important part of offsite public exposure. The projected public doses of 60Co, 137Cs and 90Sr, resulted from ground exposures are evaluated in this paper, including external exposure from ground shine and inhalation of resuspended material with radionuclides physical removal and resuspension processes considered.

Key words: nuclear power plant, nuclear accident, radionuclides, ground exposures
