Evaluation of a real-time semiconductor dosimeter and measurement of finger dose in nuclear medicine departments

In this study, the nuclear medicine staff wore one finger dosimeter placed at the base of the index finger of the working hand. When a physician injected radioisotope drugs, the finger dose was 22.4 μSv, that for radiological technologists handling ^99mTc was 29.6 μSv/day (consultation period 20 days), that for a physician injecting ¹⁸F-FDG-PET drugs was 51.3 μSv (right finger 53.9 μSv, left finger 47.2 μSv), that for pharmacists' assay of FDG was 31.5 μSv, and that for radiological technologists positioning patients was 1.9 μSv. The largest value (94.1 μSv) was observed in physicians in the case of aspiration of a delivered drug. The finger dosimeter provides an effective solution for radiation protection procedures and follow-up. All the above staff members are on rotation and do not constantly handle radioactivity throughout the year.
