ABSTRACT
In 2003, the responsibility of radiation source safety supervision was redivided and transferred from the health department to the environmental protection department. After the promulgation and implementation of the Rule on the Administration of Radiodiagnosis and Radiotherapy in 2006, due to the incorporation of a large number of medical practice supervision rules, the radiation health supervision of medical institutions has evolved into the radiodiagnosis and radiotherapy supervision. In the past 16 years, radiation, occupational health supervision, and medical practice supervision have not been well integrated, and there are many legal problems in radiodiagnosis and radiotherapy supervision. The regulation rules of environmental protection, metrology, and other relevant departments on radiation sources and radiation devices have been constantly changing, resulting in overly complex regulatory requirements on radiodiagnosis and radiotherapy, which increases the burden of medical institutions. This paper reviews the historical evolution and legal system changes of radiodiagnosis and radiotherapy supervision, analyzes the problems and challenges faced by the relevant regulatory departments, and proposes ways to improve the supervision system.
