Abstract:
A sampling survey of medical exposure frequency covered 15,000 hospitals in 24 provinces, while a sampling measurement of patient doses covered 2,000 hospitals in 14 provinces. From these surveys and measurements, we compiled survey data of 11 million cases. The data were analyzed by computer, and the frequencies, averages of skin and organic dose per examination, and population doses per capita (He, LSD, GSD, SSD) were found. The possible risks of medical exposure in China are also estimated in this paper.
