This study investigates radiation doses to interventional radiologists during CT-guided procedures, focusing on eye lens and whole-body exposure.
Simultaneous measurements of eye lens and body radiation doses during CT-guided procedures in five Finnish hospitals.
Four separate four-week measurement periods using thermoluminescent and DIS-1 dosimeters for dose assessment.
Analysis of the relationship between routinely measured doses and eye lens dose.
Overall occupational radiation exposure during procedures was negligible with proper protective measures.
One hospital reported higher radiation doses due to the use of fluoroscopy and lack of protective screens.
All hospitals maintained exposure levels below annual occupational dose limits.
