Present status of radioactive wastes from nuclear medicine in the hospitals of Guangdong province and the preliminary exploration to some relevant problems

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 131I, 125I, 99Mo-99mTc, 90Sr, 32P, 153Sm 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
