为了预测辐射受照人群中的长期效应,对他们终身所受的辐射剂量进行估计是重要的。除清理人员外,其他人群的全身剂量水平都较低。由于辐射防护原因而疏散的116 000人中,受照剂量超过50mSv的不到10%,在天然本底辐射水平高的地区生活几年也会受到这么高的辐射剂量。即使对那些继续生活在最高污染水平地区的人们来说,其终身所受的剂量仍将与此值处在同一数量级上;ICP于1990年预测的最大累积剂量当时约为160 mSv,现在估计约为120 mSv。受影响最大地区以外,这些剂量甚至更小:UNSCEAR估计70年内欧洲地区平均最高待积剂量为1.2 mSv,或为受平均本底辐射照射仅1年所致平均剂量值的一半,如下图所示。
In order to predict the long-term effects of radiation-exposed populations, it is important to estimate the radiation dose they receive over their lifetime. In addition to cleaning up the rest of the population, the systemic dose levels are low. Of the 116,000 people evacuated for radiological protection, less than 10% of doses above 50 mSv were exposed to such high doses of radiation for several years in areas with high levels of natural background radiation. Even for those who continue to live in areas with the highest levels of pollution, the lifetime dose will still be on the same order of magnitude as this figure; the maximum projected cumulative ICP dose for 1990 was about 160 mSv at this time and it is now estimated 120 mSv. These doses are even smaller outside the most affected areas: UNSCEAR estimates an average maximum target dose of 1.2 mSv for Europe in 70 years or half the average dose due to exposure to average background radiation for only 1 year, as shown in the following figure .
