Background: Occupational doses in interventional procedures guided by fluoroscopy are the highest doses registered among medical staff using x-rays. The recent Biological Effects of Ionizing Radiation (BEIR VII) report provides a framework for estimating the lifetime attributable risk (LAR) of cancer incidence from professional radiation exposure using the most current data on the health effects of radiation. Aim: to evaluate the order of magnitude of cancer risk due to professional radiation exposure in contemporary invasive cardiology practice. Methods: We interrogated the dosimetric data bank of Pisa health Physics Department, collecting data of over 2,000 exposed health professionals. We selected dosimetric data of the last 10 years (1996-2005). Effective dose (E) was expressed in milliSievert calculated from personal dose equivalent from thermoluminescent dosimetry, under apron. Whole-body LARs was estimated using the approach of BEIR VII. Results: Among the health professionals with the highest exposure, the absolute majority worked in the cath lab (see figure). For top-10 exposed staff, the median cumulative 10-year effective dose was 30-60 mSv per person, equivalent to 1,500-3,000 chest x-rays and about 15-30 years of natural background exposure. This dose gave an estimated median LAR of (fatal and non-fatal) cancer in the range of 1 cancer in 200-1 in 600 for 10 years of work in the cath lab. Conclusions: For the most experienced (and most exposed) \"top-gun\" interventional cardiologists, contemporary professional radiological exposure is associated with a non-negligible LAR of cancer. A substantial proportion of this risk can be abated with reduction of inappropriate examinations, careful optimization of procedures and implementation of simple radioprotection measures. (literal)
