Investigation on Medical Exposure Levels during the Eleventh Five-year Plan in Shanghai

Investigation on the levels of medical exposure is the basis for strengthening medical radiation protection which is increasingly highlighted.It consists of the international trend in related fields,and also adapts to the urgent need for rapid development of diagnostic radiology and radiotherapy.This article briefly introduces the methods and main aspects for studying medical exposure levels during the Eleventh Five-year Plan in Shanghai,and outlines the main findings of studies which were funded by several projects.There is no doubt that the results of the survey will play very important roles for systematic grasp of the development trend,for macro-control and full use of medical resources,for better guiding the rational implementation of diversified diagnostic radiography and radiotherapy,such as X-ray diagnosis,interventional radiology,clinical nuclear medicine and radiation oncology,and strengthening the radiological protection and safety for the growing number of examinees and patients as well as the general public against medical radiation exposures.
