Implication

Multicenter dosimetric study reveals low annual effective radiation doses in interventional radiologists, suggesting minimal occupational fatal cancer risk.

Key Points

Determine occupational effective radiation doses and assess lifetime fatal cancer risks for interventional radiologists wearing standard protective aprons.
Multicenter dosimetric evaluation involving 28 interventional radiologists across 17 institutions.
Participants wore thermoluminescent dosimeters on the collar and under lead aprons over a 2-month period.
Nonuniform exposure measurements were converted to annual effective whole-body doses based on International Commission on Radiological Protection criteria.
Mean annual effective radiation dose was 3.16 mSv (range, 0.37–10.1 mSv), approximately equal to natural background radiation (3 mSv/year) and 6% of the NCRP annual limit of 50 mSv.
Estimated annual risk of fatal cancer was less than 1 per 10,000 over nearly an entire career span.
