放射性污染衣物洗涤剂去污效果评价OACSTPCD

Decontamination of the radioactively contaminated daily clothing in nuclear industry can minimize waste,reuse resources,and reduce the radiation damage to human health.Normal commercial laundry detergents can meet the requirements for removing oil and sweat stains,but they are difficult to remove radioactive nuclides such as strontium and uranium.Currently,many foreign companies have specialized products for radioactively contaminated clothing,such as HAKA and FEVDI,but there are few in China.To solve this problem,in this work,a detergent was prepared using a self-made formula.The evaluation method on decontamination effect was established with reference to GB/T 13174 and GB/T 14057.2,and the decontamination performance of the detergent was evaluated.The homemade detergent was compared with commercially available laundry detergents.The results showed that the detergent had good decontamination effects on radioactive pollutants,reaching over 80%,and its comprehensive decontamination performance was superior to commercial laundry detergents.It had good detergency for simulated stains of oil,dust and sebum.But it had poor detergency for protein stains.This detergent could meet the requirements in daily operations of nuclear industry for decontamination of radioactive contaminants,sweat stains of workers,and oil stains of machinery and equipment,which was expected to become a new product for removing radioactive contamination from daily clothing in nuclear industry.
