Aims and objectives
The aim of this study was to determine the doses of the staff duringthe PTA of femoral artery.
According do previous studies radiologists have higher doses during fluoroscopy than other occupational groups. Research questions were: How much is the radiation dose to staff during PTA of femoral artery in interventional radiography and what is the effect of the lead shields and distance in radiation dose among staff.
The main focus in the studywas in the use of ceiling-suspended lead screen.
Methods and materials
The study was carried out in radiological department in the Oulu University Hospital.
Measurements were made in one fluoroscopy device (GE Innova) in autumn 2014. Measurements were made mostly in PTA of femoral artery but in someprocedures the PTA includes also the whole leg and pelvic artery. The doses were measured total in 12 procedures. The Dosemeters used were Philips DoseAware and Unfors EDD-30. DoseAware Dosemeters were attached on the radiologists' thyroid shield,
The average radiologist´s eye dose was 37,7 µSv,
range from 0,03 µSv to 268,5 µSv.
The average dose on radiologist´s thyroid shield was 9,91 µSv range from 0 µSv to 62,49 µSv.
The average dose on radiologist´s thyroid shield was 0,9 µSv range from 0 µSv to 6,58 µSv. Ceiling-suspended lead screen doses were on the protected side average 0,59 µSv range from 0 µSv to 1,74 µSv and on the non-protected side average 35,92 µSv range from 0,19 µSv to 113,46 µSv. The average dose rate measured from...
Overall the measured dosed were quite low in every measured point.
The mosts significant note was the careless use of the ceiling-suspended lead screen.
The Upper part of the head was exposed to the radiation almost throughout the whole procedure.
Radiologists usually protected the area that has been already protected by lead appron and thyroid shield.
This shows in the results where the doses in the radiologists eye meter arerelatively higher than in the radiologist´s thyroid shield.
