[Radiation levels in working sites where X-ray is used for medical diagnosis].
The radiation levels were measured in 109 working sites in 12 counties or municipalities of our district where X-ray was used for medical diagnosis. At the same time the effectiveness of some radioprotective facilities was assessed. The results showed that in the working sites with the ordinary protection, the average exposure rate of the surface of the worker's chest was 3.43 x 10(-8) mC/kg.s; in the sites with poor protection the average rate of exposure was the highest (about 273 x 10(-8) mC/kg.s); in the sites with other types of protection the rate was less than 10.80 x 10(-8) mC/kg.s; the exposure rate using lead chairs and aprons was 18.6 times and 5.8 times respectively lower than those without.
