In plain language
This review estimates that interventional cardiologists accumulate 50-200 mSv over a career, a projected cancer risk near 1 in 100, with high head doses. It describes a planned Italian study of cath lab staff using biomarkers; no results yet.

What it found
Cumulative occupational doses for interventional cardiologists over a 30-year career are estimated at 50 to 200 mSv, with a projected lifetime attributable excess cancer risk of about 1 in 100.
Key figures: 50 to 200 mSv; 1 in 100
Interventional cardiologists receive two to ten times the annual exposure of diagnostic radiologists.
Key figures: two to ten times higher
The operator's left side is more exposed than the right, and less protected body parts such as the head and hands can receive 5 to 50 mSv per year.
Key figures: 30% to 100%; 5 and 50 mSv per year
Annual head exposure for interventional cardiologists is cited at 20-30 mSv, and higher without a ceiling-suspended screen.
Key figures: 20-30 mSv per year
The planned Healthy Cath Lab case-control study will enrol 500 highly exposed cath lab staff (>3 years) and 500 matched unexposed controls, using a web survey and surrogate biomarkers.
Key figures: 500 exposed, 500 controls
Limits to keep in mind
Narrative review and study-protocol rationale with no new data; risk figures are projections or drawn from cited studies, some observational and small, and the planned case-control study had not reported results.
