OCCUPATIONAL EXPOSURE TO X AND GAMMA RAYS IN POLAND IN 2010

摘要

abstract_textpBackground: The paper presents the results of the measurements of ionizing radiation doses received by people occupationally exposed to X and gamma rays in Poland 2010 provided by the Nofer Institute of Occupational Medicine in Lodz. Materials and methods: The personal dose equivalent Hp(10) measurements were performed using the film method while the Hp(0.07) measurements using ring dosimeters with TL detectors according to the accreditation procedures (No. AB327). The measurements were carried out over two-month periods for Hp(10) and over one- or two-month periods for Hp(0.07). Results: In 2010 the Nofer Institute of Occupational Medicine in Lodz covered more than 27,000 workers with individual whole body dosimetry Hp(10) in 3808 laboratories and 1800 workers with hands dosimetry Hp(0.07) in 152 laboratories. Mean annual dose Hp(10) was 0.5 mSv (annual limit for Hp(10) equals 20mSv), whereas for Hp(0.07) was 5.6 mSv (annual limit for Hp(0.07) equals 500 mSv). Conclusions: In 2010, doses higher than the annual limit for both Hp(10) and Hp(0.07) were not recorded. The collected data confirm that the radiation protection of people occupationally exposed to X and gamma rays is satisfactory in Poland. Med Pr 2011;62(6):579-582/p/abstract_text
