Following the recommendations of the International Commission on Radiological Protection (ICRP), interest in radiation exposure to the eye lens has increased [1]. The International Atomic Energy Agency (IAEA) has identified five medical procedures that require particular attention to minimize lens exposure, one of which is nuclear medicine examinations [2]. Among various medical tasks, nuclear medicine procedures are associated with relativeely high occupational radiation exposure (Fig. 1) [3]. However, research specifically addressing lens exposure among medical staff remains limited compared to other procedures [4,5].

This study aims to assess the current radiation exposure levels of radiological technologists and nurses involved in nuclear medicine examinations. In routine practice, dosimeters are selected based on measurement objectives (Fig. 2). To improve the accuracy of lens exposure assessment, we used a dedicated eye lens dosimeter in this study. The results were compared with those obtained from conventional personal dosimeters to evaluate the effectiveness of existing measurement methods. Additionally, we analyzed the correlation between workload and radiation exposure levels.
