Abstract: This paper reviews the rapid development of various types of Radiodiagnosis and Radiotherapy in China and aboard, which leads to a dramatic increase of application frequency of medical exposure. Then summaries the trend found through the investigation on the medical exposure levels during the Eleventh Five-year Plan in Shanghai. According to the above analysis, suggestions to strengthen the medical exposure protection are proposed. When the X-ray diagnosis, interventional radiology, nuclear medicine and radiation oncology become indispensable means to modern medicine, the public exposure due to health examinations and disease diagnosis or treatments has been institutions undergoing X-ray diagnosis in Shanghai by the year of 2010, 2.1 more times of that in 1998. During this period, the total number of X-ray diagnosis equipment increased by 57.7%, and the number of X-CT scanners increased by 131.9%. The annual application frequency of X-ray diagnosis was 780.44 person·time for per 1 000 population in 2009. Compared with the data in 1996, the total frequency increased by 58.3%, and the frequency of X-CT scans increased 317.1%. In clinical nuclear medicine, compared with the data in 1996, the annual application frequencies increased by 139.4% and 210.6% for diagnosis and therapy in 2008, respectively. In the field of radiation oncology, the annual frequency also increased by 59.9% during the same period. Shanghai pioneered the survey on medical exposure levels during the Eleventh Five-Year Plan period in China, and has accumulated a lot of valuable new information and mastered the development trends of medical exposure. This work lays a solid foundation for effectively strengthening the radiation protection from medical exposure, provides a scientific basis for the rational planning and utilization of health care resources. Meanwhile, this work is also very useful for promoting the healthy development of radiology career while avoiding disadvantages and to the benefit of the people.
