本文介绍一种简单方法,利用事先准备好的图表和数据来迅速查算出反应堆事故下公众可能受到的预期全身剂量和甲状腺剂量。一、引言在反应堆事故中,放射性碘和惰性气体加上少量粒子有可能释放到大气环境中去,并可能超过规定的限值。在这种情况下,必须迅速决定是否采取防护行动来保护公众。采取何种防护行动,在某种程度上取决于公众成员可能接受的预期辐射剂量。因此,必 This article presents a simple way to quickly calculate the expected systemic and thyroid doses to the general public under a reactor accident using pre-prepared charts and data. I. INTRODUCTION In the event of a reactor accident, radioactive iodine and inert gases plus small quantities of particles may be released into the atmosphere and may exceed prescribed limits. In such circumstances, it must be promptly decided whether to take protective actions to protect the public. Depending on the expected radiation dose that members of the public may accept, the protective measures taken are, to a certain extent, Therefore, must
