[Occupational exposureto X and gamma rays in Poland in 2010].

BACKGROUND

The paper presents the results of the measurements of ionizing radiation doses received by people occupationally exposed to X and y rays in Poland 2010 provided by the Nofer Institute of Occupational Medicine in Łódź.

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 20 mSv), 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.
