In plain language
This 2004 review reports that most small studies found more chromosomal DNA damage in hospital staff with chronic low-dose radiation exposure, including interventional cardiologists, while ultrasound showed no consistent genetic effect. Biomarkers are not proven health outcomes.

What it found
Most cytogenetic studies of hospital workers chronically exposed to low-dose ionizing radiation report increased somatic DNA damage, though most failed to show a dose-effect relationship.
Interventional cardiologists and electrophysiologists have the highest occupational radiation exposure among health professionals.
Head dose to cardiologists can be high and may exceed the eye lens limit then recommended.
Key figures: up to 60 mSv per year; limit 150 mSv per year
There is no consistent evidence that medical ultrasound causes genetic effects in clinical staff, although one study of Doppler staff showed increased genotoxic damage.
Physicians, including cardiologists, show poor knowledge of radiation doses and risks.
Key figures: 11%, 5%, 29% and 42% correct
Limits to keep in mind
Narrative review without systematic search; the cited cytogenetic studies are small, mostly lack dose-response relationships, and measure biomarkers rather than health outcomes.
