“…This demonstrates that high doses to the extremities do not just occur in exceptional cases. Finger or hand doses of more than 1 mSv have also been published by Felmlee et al [1] and Whitby and Martin [8].…”

“…Several investigations [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] revealed that the doses to medical staff in interventional radiology and cardiology may be of concern from a radiation hygiene point of view. Partial-body doses reported ranged from a few microsieverts up to a few millisieverts per procedure, with higher values occurring mainly for the hands.…”

Radiation exposure of medical staff from interventional x-ray procedures: a multicentre study

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) microSv for an unshielded person; the partial-body dose per procedure was 2.8 (240) microSv to the eye lens, 4.1 (730) microSv to the thyroid, 44 (1,800) microSv to one of the feet and 75 (13,000) microSv 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.

“…2,3 Interventional radiologists have the potential to receive significant radiation doses. 4,5 However, the level of knowledge of radiation risks decreases dramatically outside of the specialist environment of the radiology department with most doctors underestimating the radiation doses associated with a variety of radiological investigations. 6 There are few reports for the radiation risk associated with the use of x-ray usage outside the specialized environment of the radiological department.…”

Radiation Exposure and the Urologist: What Are the Risks?

Fluoroscopic screening results in radiation exposure of medical personnel. The estimate of maximum scatter radiation exposure to the surgeon for 50 PCNL procedures a year did not exceed 10 mGy. This amount is less than 2% of permissible annual limits of equivalent dose to the extremities. Medical personnel should be aware of scatter radiation risks and minimize radiation exposure when involved in fluoroscopic screening procedures.

“…Despite the fact that, during recent years, a number of efforts have been put into the protection of both patients and staff, information about radiation exposure during ERCP remains scarce. Published work on radiation protection in IR is mainly focussed on various angiographic and cardiological procedures [5][6][7][8][9][10][11][12][13][14][15][16]. Few international papers have been published that evaluate radiation exposure to patients [7,[17][18][19][20] and staff [21][22][23] during ERCP.…”

Despite a number of efforts being put into the radiological protection of both patient and staff during interventional radiological (IR) procedures during recent years, information about radiation exposure during endoscopic retrograde cholangiopancreatography (ERCP) procedures remains scarce. The purpose of this study was to estimate both patient and staff radiation doses during therapeutic ERCP procedures by direct measurement and to compare these results with data from other IR procedures. For 54 patients, effective dose and skin dose were estimated by measuring the dose-area product. For staff, entrance surface doses to the lens of the eye, thyroid and hands were estimated by thermoluminescent dosemeters. A median effective dose of 7.3 mSv and a median entrance surface dose of 271 mGy per procedure were estimated for patients. The gastroenterologist received a median dose of 0.34 mGy to the lens of the eye, 0.30 mGy to the skin at the level of the thyroid and 0.44 mGy to the skin of the hands, per procedure. When comparing the dosimetric quantities presented in this study with data from other IR procedures, it is clear that patient skin doses and doses to staff are high owing to the use of inappropriate X-ray equipment. ERCP requires the same radiation protection practice as all IR procedures. It should be consistently included in future multicentre IR patient and staff dose survey studies at national or international level.
