液态放射性污染主要指加速器冷却循环水受中子照射被活化形成放射性物质；固体放射性污染为热室工作箱内的模板，退役加速器离子源、准直器和靶周围被活化的器件及与放射性制剂分装、注射相关的用品；放射性气态污染，主要指中子使空气活化产生核素11C、13N、15O、41Ar，空气中其它成份被中子活化产额低，多为气溶胶状态；另外放射性表面污染主要指加速器厅内被活化的固体器件，冷却水破裂或放射性药物意外污染，有关传递通道和贮源容器的表面放射性污染。

Great attention has been paid to the threat of the highly radioactive and the low-level radioactive waste from nuclear industry and the radioactive waste has become a more and more serious problem with the waste from medical industry and research institutions. The uranium from uranium minings has caused the pollution of groundwater around.

核工业生产中产生的高、中、低放废物对环境构成的威胁越来越受到重视，它们与医疗、科研、国防事业的核废物一起成为越来越严重的环境问题，尤其是铀矿冶中产生的U对地下水的污染。

The financial fallout has begun, and the political fallout may not be far behind.

That is a lot better than nothing, at least for nuclear fallout (for which the model was first developed): there the case for being safe not sorry is overwhelming, and once the fallout has fallen, a Geiger counter will tell you whether the model's forecasts of which places would be affected have turned out to be right.

但是，有个宽泛的概念总比什么都没有好，至少对核放射性微尘是如此，而这种电脑模型最初就是为核放射性微尘而研制出的，因为在这方面，未雨绸缪显得十分重要。且一旦放射性微尘沉降下来，盖格计数器就会告诉你模型所预报的受影响地区是否准确。
