本市某从事硝酸钍生产的化工厂,操作工人工作服均受不同程度的沾染,有的沾染水平甚至超过控制标准数倍至数十倍。工作服的沾污不但可引起周围环境和空气的污染。还有可能进入体内,造成内照射的危害,为避免工作人员因受到钍沾染而造成内外辐照的危害,以确保身体健康,我们进行了工作服去除钍沾染的研究工作。工作分四个方面进行。 The city of a chemical plant engaged in the production of thorium nitrate, workers operating clothing workers are subject to varying degrees of contamination, and some contamination levels even exceed the control standard several times to several times. Pollution of work clothes can not only cause the surrounding environment and air pollution. There is also the possibility of entering the body, resulting in the dangers of internal irradiation. In order to avoid the harm caused by internal and external radiation caused by the thorium contamination of workers, to ensure good health, we carried out research work on the removal of thorium from working clothes. Work in four areas.
