External occupational radiation exposure in the GDR in 1987

In 1987, a total of 37145 radiation workers were monitored by the film badge service of the National Board of Atomic Safety and Radiation Protection. None of the external gamma- or X-ray doses were found to exceed the secondary limit of 50 mSv in a year with 97.8% of them remaining below 1/10 of this value. 105 workers received doses from electrons which did not exceed 3/10 of the secondary limit of 500 mSv/year for the maximum surface dose. Additional data obtained by monitoring 1161 radiation workers with finger-ring dosemeters demonstrated that hand exposures in no case exceeded the secondary limit of 500 mSv/year. The annual dose data have been presented in tabular form by dose range, type of establishment, and field of application. Also given were annual collective doses, annual average doses and special collective dose quotients for workers in important fields of application of ionizing radiation. 10 tabs. (author)
