某单位从事特种核放射工作,其工作条件比较特殊,平时直接接触辐射环境的时间较短,一旦执行特殊任务,需要持续在辐射条件下工作数天或数十天,受照剂量比较大。经临床检查发现,从事特种核放射工作2年以上,多出现明显的无力型神经衰弱。外周血象经半年以上多次动态观察,白细胞总数逐渐降低,经肾上腺素白细胞激发试验为真性白细胞减少。1991年4月～8月,我们采用贞芪扶
A unit is engaged in special nuclear radiation work. Its working conditions are rather special. It usually has a short period of direct contact with the radiation environment. Once a special task is performed, it needs to continue working under radiation conditions for days or dozens of days, and the radiation dose is relatively large. After clinical examination, it was found that in the special nuclear radiation work more than 2 years, there was more obvious weakness of neurasthenia. Peripheral haemorrhages were observed dynamically for more than half a year. The total number of white blood cells gradually decreased, and the leukocyte reduction was confirmed by epinephrine white blood cell provocation test. In April-August 1991, we adopted the Junggar
