Abstract: | The purpose of this study was to analyse the radiation exposure of medical staff from interventional x-ray procedures. Partial-body
dose measurements were performed with thermoluminescent dosimeters (TLD) in 39 physicians and nine assistants conducting 73
interventional procedures of nine different types in 14 hospitals in Germany. Fluoroscopy time and the dose–area product (DAP)
were recorded too. The median (maximum) equivalent body dose per procedure was 16 (2,500) μSv for an unshielded person; the
partial-body dose per procedure was 2.8 (240) μSv to the eye lens, 4.1 (730) μSv to the thyroid, 44 (1,800) μSv to one of
the feet and 75 (13,000) μSv to one of the hands. A weak correlation between fluoroscopy time or DAP and the mean TLD dose
was observed. Generally, the doses were within an acceptable range from a radiation hygiene point of view. However, relatively
high exposures were measured to the hand in some cases and could cause a partial-body dose above the annual dose limit of
500 mSv. Thus, the use of finger dosimeters is strongly recommended. |
