Occupational exposure in operational radiology.
Measurements of dose-rate on the body surface of workers engaged in operational radiology permit the assessment of average annual effective dose equivalent, and dose equivalents in eye lenses and in hands. Measurements were made in 20 hospitals in the course of different operations in which x-radiation was used. Individual values of annual effective dose equivalent ranged from about 0.1 to about 45 mSv. In the majority of cases this did not exceed 5 mSv at the current workload. For the eye lens, the respective dose equivalent range was from 0.01 to about 70 mSv; only in one case, due to the engagement of a totally inappropriate operating procedure, could the eye dose reach 1.9 Sv per year. The individual values of the dose equivalent to hands ranged from 0.5 to 140 mSv.
