“…These employees are included in the system of monitoring of individual exposure to radiation (Piwowarska-Bilska et al 2010). The average annual doses received by workers in the nuclear medicine who work with open sources of radiation can be relatively high compared to other professional groups, also working under exposure to ionizing radiation (Al-Haj and Lagarde 2002, Croft and Lefuare 2002, Martins et al 2007, Valuckas et al 2007, Velasques de Oliveira et al 2007, Wrzesień and Olszewski 2008, 2012. Therefore, such workers in particular must be inspected for occupational risk of exposure, and the effectiveness of this control measure should be analysed.…”

Positron emission tomography (PET) is now one of the most important methods in the diagnosis of cancer diseases. Due to the rapid growth of PET/CT centres in Poland in less than a decade, radiation protection and, consequently, the assessment of worker exposure to ionising radiation, emitted mainly by the isotope (18)F, have become essential issues. The main aim of the study was to analyse the doses received by workers employed in the Medical Diagnostic Centre. The analysis comprises a physicist, three nurses, three physicians, three technicians, as well as two administrative staff employees. High-sensitivity thermoluminescent detectors (TLDs) were used to measure the doses for medical staff. The personnel was classified into categories, among them employees having direct contact with the 'source of radiation'-(18)FDG. The TLDs were placed on the fingertips of both hands and they were also attached at the level of eye lenses, thyroid and gonads depending on the assigned category. The highest dose of radiation was observed during the administration of the (18)FDG to the patients. In the case of the physicist, the highest dose was recorded during preparation of the radiopharmaceutical-(18)FDG. The body parts most exposed to ionizing radiation are the fingertips of the thumb, index and middle finger.

Low density polyethylene films were grafted by poly (acrylic acid). The effects of dose, monomer concentration, solvent, inhibitor and thickness of films were investigated. Adsorption capacities of grafted films of Pb 2þ and Cd 2þ reached up to 20 and 13 (mg/g), respectively. The complexed grafted films in protection of workers against technetium-99 m radiation dangers were investigated. The effects of grafting percentage, thickness and adsorption capacity of ions on shielding efficiency were studied. The transmission intensity of complexed grafted films decreased gradually until arrived almost 0%. The protection efficiency of complexed grafted films is higher than grafted and virgin films, respectively.

The appropriate radiation protection measures applied in departments of nuclear medicine should lead to a reduction in doses received by the employees. During 1991-2007, at the Department of Nuclear Medicine of Pomeranian Medical University (Szczecin, Poland), nurses received on average two-times higher (4.6 mSv) annual doses to the whole body than those received by radiopharmacy technicians. The purpose of this work was to examine whether implementation of changes in the radiation protection protocol will considerably influence the reduction in whole-body doses received by the staff that are the most exposed. A reduction in nurses' exposure by ~63 % took place in 2008-11, whereas the exposure of radiopharmacy technicians grew by no more than 22 % in comparison with that in the period 1991-2007. Proper reorganisation of the work in departments of nuclear medicine can considerably affect dose reduction and bring about equal distribution of the exposure.
