广东省医院核医学放射性“三废”现状及有关问题初探

PRESENT STATUS OF RADIOACTIVE WASTES FROM NUCLEAR MEDICINE IN THE HOSPITALS OF GUANGDONG PROVINCE AND THE PRELIMINARY EXPLORATION TO SOME RELEVANT PROBLEMS

广东省是我国核医学较为发达的地区，在全省医疗系统中设置核医学科（室）的医院有约５０家（不包括只从事放免分析的医院），拥有发射计算机断层仪（ＳＰＥＣＴ）４０余台，主要使用１３１Ｉ、１２５Ｉ、９９Ｍｏ－９９ｍＴｃ、９０Ｓｒ、３２Ｐ、１５３Ｓｍ等１０多种放射性同位素。本文在笔者参加广东省换（核）发《放射性药品使用许可证》工作的基础上，调查和总结了全省医院核医学科放射性药品使用情况和放射性“三废”排放、处理的情况，并就当前各医院在放射性“三废”管理和处理方面存在的问题进行了初步探讨，提出了加强对医院放射性“三废”排放进行监督管理的一些对策和建议。

In Guangdong province of China nuclear medicine is quite developed. There are about 50 hospitals (not including the hospitals only with radioimmunoassay) in the medical units of Guangdong province which have their own nuclear medical departments. More than 40 ECTs are owned by the hospitals and more than 10 radioisotopes, such as 131 I, 125 I, 99 Mo 99m Tc, 90 Sr, 32 P, 153 Sm etc., are mainly used.The thesis, based on the author's work in checking the use of radiopharmaceuticals in the hospitals of Guangdong province, investigates and summarizes the actual situations of the use of radiopharmaceuticals and the discharge and treatment of radioactive wastes in nuclear medical departments of the hospitals in Guangdong province. According to the actual problems in administration and disposal of the radioactive wastes in the hospitals, it makes a preliminary exploration and puts forward some countermeasures and suggestions on how to supervise and administer the discharge of radioactive wastes in the hospitals, and how to further solve them, in order to prevent and reduce the radioactive contamination and damage to the environment and the public caused by the development of nuclear medicine.
