  • Title: [Assessment of radiation exposure of miners to radon and its daughter products in selected non-ferrous metal mines].
    Author: Olszewski J, Kacprzyk J, Kamiński Z.
    Journal: Med Pr; 2010; 61(6):635-9. PubMed ID: 21452566.
    Abstract:
    BACKGROUND: For over 40 years already, the Nofer Institute of Occupational Medicine (NIOM) in Lodz has been supervising non-ferrous metal mines for miners' radiation risk of radon and its short-lived daughters products found in the air of mines. MATERIAL AND METHOD: The supervision involves the use of trace detectors placed in passive dosemeters worn by a representative group of miners. RESULTS: During the late 1960s, the exposure in some mines was as high as 50 mSv/year. Owing to the steps undertaken in the mines, including primarily the provision of improved ventilation systems, the exposure was reduced to 5 mSv/year, and then to 2 mSv/year during the 1980s and 1990s. CONCLUSION: The results of measurements, performed during the recent 10 years, show that the exposure in non-ferrous metal mines is now within the limits specified for worker category B, i.e., not exceeding 6 mSv/year. The mean annual effective dose for a ten-year (1998-2009) period was 2.1 +/- 0.9 mSv/year.
