某稀土冶炼厂放射卫生现状调查

Report on Radiological Health Investigation of the Workers in a Rare-earth Refinery Factory

报道了对某稀土冶炼厂辐射环境和职业性查体调查结果。调查的主要内容有环境放射性检测与评价,工人肺内钍沉积量测定及其对健康的影响。调查结果表明该厂4个接尘车间属于放射性工作场所,9名接尘工人肺内钍沉积量超过1个调查水平(2.22Bq),未发现接尘工人中出现尘肺,其外周血象和肝功能均未发现异常。

The paper presents an investigation on the thorium lung burden and its health effects on the workers in a rare-earth refinery factory. The results show that the four workshops are thought to be the radiation workplaces. The thorium hmg burden of 9 dust-exposed workers is higher than one investigation level （2.22 Bq） and the highest one is 3.33 Bq. The results of radiography, hematological parameters and hepatic parameters for the dust-exposed workers examined are all within the normal range.
