Relationship of Dosimetry in Personnel Occupationally Exposed Radioimmunoassay Laboratory and Radiopharmacy

The objective of this study was to know the variation in the five-year radiation exposure data. A retrospective analysis was carried out of the results of occupational exposures during the years 2009-2013, of the personnel in the Radioimmunoassay and radiopharmacy labs of the Institute of Nuclear Medicine. The results which were submitted by the Bolivian Institute of Nuclear Science (Laboratory dosimetry personal). The readings of personnel dosimeters (TLD) of Radioimmunoassay and radiopharmacy are reported on quarterly basis. The aim of this study was to see correlation for the variation of the results of exposure during the last 5 years. It was noted that in the laboratory of radioinmunoanalis that it had a value of 0.7 mSv in relation to the laboratory for radiopharmacy which was 1.9 mSv, there is a variation of 1.0, because in radiopharmacy working with ^99mTc, with energy of 140 keV, in comparison to the laboratory of Radioimmunoassay which works with ¹²⁵I, with 35 keV energy. In both laboratories of the Institute of Nuclear Medicine, radiation protection standards, and proper use of individual dosimeter are made as documentation indicates institutional licensing. The continuous refreshing / updating of knowledge of radiation protection is important for the workers occupationally exposed, to reduce the risks of exposure to radiation. (author)
