目的:我们在本市一些使用放射性物质的工厂中,看到他们一般都用草酸作去污剂,不仅去污效率很差,而且腐蚀皮肤,对工作人员的健康十分不利。为了寻求好的去污剂及其合适浓度,我们和工人同志一道在现场对比进行优选。 Objectives: In some factories in the city that use radioactive substances, we found that they generally use oxalic acid as a detergent, which not only has poor decontamination efficiency but also corrodes the skin and is very detrimental to the health of staff. In order to find a good detergent and its appropriate concentration, we work together with the workers comrades in the field to optimize the comparison.
