[en] Some definitions of physical quantities connected with individual dosimetric control of workers being exposed to ionizing radiation have been performed. The review of most often used personal dosemeters has been done in four categories: photographic dosemeters, thermoluminescent dosemeters, radio-photo-luminescent dosemeters and electronic ones

[en] In 1999 about 6208 radiation workers from 389 departments were monitored by CLOR in Poland. The distribution of annual personal doses shows that 85% of controlled workers received doses below the MDL (0.4 mSv) and about 97% controlled workers received doses below 5 mSv. Doses higher than 50 mSv were received by three operators of industrial radiography units. The radiation workers under control are divided into four main work sectors: nuclear industry, research and education, medicine, and general industry. The average annual dose for all workers in each particular sector was 0.22 mSv, 0.22 mSv, 0.30 mSv and 0.80 mSv, respectively. The average annual dose for the entire monitored population was 0.47 mSv. The average annual dose in each particular sector for number of workers receiving E>0, i.e. H_p(10) (0.4 mSv, amounted to 1.78 mSv, 2.03 mSv, 1.88 mSv and 4.85 mSv, respectively. The average annual dose for the full number of workers receiving E>0 was 3.21 mSv. This paper contains the detailed analysis of occupational exposure. The distributions of annual occupational exposure in different work sectors are also given. (author)

[en] Fluorescent glasses have been developed containing various amounts of Mn or Sm to be used as fluorescence standards in RPL detector readers. The properties of the glasses were investigated by determining the light absorption spectra, the UV and gamma radiation excited fluorescence spectra, changes in the intensity of fluorescence measured with a RPL detector reader as a function of the glass temperature and those brought about by light and gamma irradiation. The results indicate that the standards prepared are of high quality and they are not inferior to those used in the Toshiba reader. (author)

[en] Due to the higher neutron energies encountered in the stray field around high-energy proton accelerators the use of the LR115 cellulose nitrate film as an element of the personnel dosimeter seems promising. In order to cover the lower energy end of the spectrum the LR115 is complemented by a TLD pair (⁶LiF/⁷LiF). A thorough investigation into the properties of the plastic detector (i.e., energy response, effect of different radiatiors, background, fading, development conditions, and determination of the optimum reading conditions) was followed by a pilot project in which practical experience in the field was accumulated. Wearing the film in parallel with the NTA film allowed a comparison between the two dosimeters
