Occupational and environmental radiation and cancer.

摘要: Epidemiologic evidence on the relation between occupational and environmental radiation cancer is reviewed. Studies of pioneering workers, underground miners, radium dial painters revealed excess deaths contributed to setting protection standards theories carcinogenesis. Occupational exposures today are generally much lower than in past, thus any associated increases will be difficult detect. Pooling investigations these more recently exposed however, has potential validate current estimates risk used protection. New information effects chronic exposure also may come from studies former Soviet Union Chernobyl clean-up workers at Mayak nuclear facilities. exposures, other radon, largely inconclusive, due mainly difficulties detecting low risks with dose exposures. Thyroid cancer, been linked accident weapons tests. Low-level released during normal operations plants not found increase rates surrounding populations. Radon, a human carcinogen, most ubiquitous populations; remediating high residential-radon levels recommended, recognizing that can never removed completely because it occurs naturally.
