Dose assessments were performed using two types of personal dosimeters: the Bertin miniTRACE γ and the POLIMASTER PM1703MO-1 RED FLASH . Measurements collected from these devices during daily procedures enabled a quantitative analysis of occupational exposure under real working conditions. A comparative evaluation of the recorded values was conducted to assess the consistency, reliability, and precision of the two dosimetry systems. This comparison also provided insight into radiation protection practices within the department and helped verify whether operator exposure levels remained within recommended safety limits. The results demonstrated good agreement between the devices, confirming their reliability and suitability for monitoring occupational exposure in nuclear medicine settings. The highest dose levels were observed during radiopharmaceutical preparation and injection procedures, particularly during dose administration to patients, which represents the most irradiating step for the operator. These findings highlight the importance of strict adherence to radioprotection principles, including time optimization, distance maximization, and appropriate shielding. Furthermore, the study emphasizes the necessity of maintaining dedicated protective equipment to ensure both operator safety and optimal patient management. Overall, the dosimeters proved to be effective tools for routine radiation monitoring and quality assurance in nuclear medicine practice.
