The goal of our investigation was to determine the amount of hand and whole-body radiation exposure incurred from the performance of various job duties. Methods: Whole-body and hand exposures were recorded over a 15–16 mo period using thermoluminescent dosimeters. Radiation exposure readings were collected in four different areas, nuclear pharmacy, radiopharmaceutical injection, nuclear cardiology and general nuclear medicine. Results: Monitoring showed that higher hand exposure is caused by direct handling and injecting of radiopharmaceuticals. Whole-body exposure also increases, but correlates more closely to body shielding than to actual hand exposure. Higher whole-body exposure was seen in nuclear cardiology when compared to general nuclear medicine, even though general nuclear medicine performed three times the study load of nuclear cardiology. Conclusions: In an area where imaging is the primary job duty of the NMT, the time of direct patient contact seems to be the principal factor affecting whole-body exposure. Although hand exposure increases with the amount of radioactivity handled in an area where handling radiopharmaceuticals is the main job duty of the NMT, whole-body exposure correlates more closely to body shielding than to the amount of radioactivity handled.
