关于应用镭源时对人体的危害,国外已有大量资料介绍。但是,镭生产过程中对工人的影响资料报道较少。我校于1973至1975年对某厂进行了三年的调查,初步报告如下。 辐射防护与剂量调查 该厂是从铀等重金属元素中分离、提纯镭的工厂,由于镭属极毒元素,射线强度较大,安全防护措施虽较好,但仍有些地方超出了国家规定的最大容许水平。工作场所辐射水平参见表1。
On the application of radium hazard to the human body, a large number of foreign countries have introduced information. However, there are few reports on the impact of workers on radium production. Our school from 1973 to 1975 for a three-year investigation of a plant, the initial report is as follows. Radiation protection and dose survey The plant is from the uranium and other heavy metal elements in the separation and purification of radium factory, due to radium is extremely toxic elements, radiation intensity is larger, although the safety precautions are good, but there are still some places beyond the state’s maximum Allowable level. Table 1 shows the level of radiation in the workplace.
