近几年来,在我国,稀土球墨铸铁得到了迅速推广,特别是许多单位都是土法上马,采用稀土合金多系手工破碎,手工操作,因此在稀土合金的存放,破碎、熔炼和应用过程中,对稀土元素的放射性应采取的卫生防护措施必须引起注意。现将我们在生产现场对稀土元素的放射性的测定结果和应采取的放射性卫生防护措施介绍如下。 In recent years, rare earth nodular cast iron has been rapidly popularized in our country. In particular, many units are started with indigenous methods and used rare earth alloys to process and crush them manually. Therefore, during the storage, crushing, smelting and application of rare earth alloys , The protective measures against radioactivity of rare earth elements must pay attention. Now we in the production site of radioactive determination of rare earth elements and should take the radioactive protective measures are described below.
