庆保 周, 余升 吴, 宝贵 周, et al. 超声波洗涤去除放射性核素沾染的初步实验研究[J]. 核技术, 1981, 04(4): 47-49.
放射性核素在医学科学领域的应用日益广泛,无论是临床诊断、治疗和实验室科研工作都在愈来愈多地运用放射性核素,而在各种检查治疗和实验过程中所沾染的容器、器皿的去污就成为从事放射性核素工作中一个急需解决的问题。直到目前为止,医院同位素室和其他实验室仍以手工清洗为主,手工清洗很费时间,我们曾将

I污染的试管、注射器用手工清洗,去污效果仅35~61%,且增加了工作人员的受照剂量。为了寻求一种安全、简便有效的去污方法,我们进行了超声波去除放射性同位素沾染效果的观察,比较了不同功率、不同超声洗涤时间、不同放射性核素、不同器具的超声去污效果,证明超声波去沾污,不仅效果较好

,而且工作人员接触放射性时间为手工清洗的二十分之一。
The widespread use of radionuclides in clinic and research stimulates searching for new methods of cleaning the contaminated utensils.
In this experiment
a 250W ultrasonic scrubber was used. Contaminated utensils was cleaned in detergent solution for 5 min. Then washed by water for 5 min. The results showed that the decontaminating method is effective and economic and eliminate unnessary exposure to ionizing radiation. But it is not satisfactory for that of
