Investigation on radiation protection situation for nuclear medicine in cities of eastern China

Most of the current investigations on radiation protection for nuclear medicine in China were limited to a single medical institution or a small-scale area. The conclusions obtained were rather one-sided. To be more comprehensive and representative, a total of 28 medical institutions in 7 provinces/municipalities in the eastern part of China were selected and a field research on nuclear medicine departments were conducted in our study. We investigated the following aspects in 28 hospitals including site setting, equipment configuration, sources of radionuclide, site monitoring and current status of radiation protection management. It was found that some hospitals had problems in unreasonable site selection, poor equipment condition and imperfect performance testing. More attention should be paid to such problems in future radiation protection and supervision work while corresponding solutions should be proposed too. (authors)
