Abstract
Underground uranium mining was performed in East Germany after World War II on a large scale. East Germany was the main supplier of uranium for the Soviet Union. This review gives a historical summary and describes the broad spectrum of exposure to potential health hazards and the health consequences. Working conditions were very poor during the postwar years from approximately 1946-1955: there was drilling with air floating and a lack of forced ventilation. Dust levels were very high and there was a significant inhalative incorporation of alpha-radiating substances, mostly from short-lived radon progeny. However, long-lived alpha-radiating substances such as uranium-238 contributed considerably to the radiation dose. There was also exposure to toxic chemicals, such as arsenic (in some mines) or crystalline silica, and a variety of other health hazards. From approximately 1956-1970, mining conditions improved: there was drilling with the addition of water and forced ventilation of the mines. As of approximately 1970, compliance with rules of industrial hygiene and international standards of radiation protection was evident. In 1990, uranium production was generally stopped. To date, more than 5,000 cases of bronchial carcinoma are accepted as compensable occupational diseases and more are expected. The extensive data from Wismut uranium mining could improve our understanding of a complex exposure situation resulting in a variety of health impairments other than lung cancer.
