During firefighting and rescue operations there is a high probability that rescuers will come into contact with ionizing radiation and radiation contamination. The firemen of the State Fire Service and the Volunteer Fire Service perform a number of tasks during the action [Obwieszczenie Marszałka Sejmu… 2009], for which they are prepared during exercises and theoretical sessions. A significant reduction in the probability of radiation or radiation contamination risk can be achieved by taking appropriate precautions and following certain rules and procedures. The actions at which ionizing radiation occurs take place very rarely and procedures are regulated by the “Rules of conduct in the event of radiation risk” [Komenda Główna… 2009] annexed to the “Rules of the organization of chemical and environmental rescue in the National Firefighting and Rescue System” [Komenda Główna… 2013]. The aim of this article is to present the possibilities of protecting the rescue team during fire and rescue operations associated with the potential presence of radioactive materials at the scene.

Objectives While working with cyclotrons used for the production of radiopharmaceuticals, workers can experience significant exposure to the adverse effects of ionizing radiation. The aim of this paper was to determine the typical level of such exposure received by such personnel while servicing cyclotrons. Material and Methods Exposure was assessed using TLD detectors placed in an anthropomorphic phantom, as well as dose meter to determine whole body and eye lens exposure. The phantom was placed in locations receiving the greatest exposure to ionizing radiation during service activities. The time spent by employees during servicing was assessed based on routine visits by service technicians. The obtained results were compared with readings of detectors worn by employees during service activities. Results The highest equivalent doses in the thoracic area were found to be received by the lungs (211.16 μSv/year). In the head and neck area, the highest dose was measured in the eye lens (3410 μSv/year). The effective dose for the whole body was found to be 1154.4 μSv/year, based on the phantom, and 149 μSv per service visit (1192 μSv/year), based on the dose meters carried by the workers. Conclusions Service workers are exposed to significant doses of ionizing radiation, representing a clear radiological protection issue. To reduce exposure to eye lenses, it is recommended to use protective goggles when working with highly-radioactive elements.
