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 are relatively higher than in the radiologist´s thyroid shield.
The use of lead-shield in the operation room and personal radiation protection is called active radiation protection (Bartal,
Paolo & Miller 2014,
Radiographers dose was low in every procedure due to the distance from the radiation source.
Difference in doses measured from radiologist´s and radiographer´s thyroid shield was average 9 µSv.
Keeping the distance from the radiation source is the only way how radiographer can affect on his/hers radiation exposure.
Radiologist uses the fluoroscopy device.
On the other hand radiographers could also say to radiographer about the use of the fluoroscopy device and the ceiling-suspended lead-screen.
Radiographers are professionals in the radiation protection.
The use of active dosemeters can be an answer to help the staff to estimate their exposure to the radiation (Chiriotti,
Duch & Sempau,
The accumulated doses and dose rates measured from the radiologist´s eye meter were relatively high compared to the doses and dose rates measured from the unprotected side of the ceiling suspended lead-screen.
Reasons for this are demonstrated in the pictures. (Fig. 3 and 4.)
It seems that low doses of radiation can affect brain tumours to interventional cardiologists (Roguin,
Goldstein & Bar,
Could this be possible also among interventional radiologists,
because their left side of the head is also exposed to the radiation.
Yearly nearly 300 PTA of femoral artery are made in Oulu University Hospital,
so by proper use of the lead shields the doses could be even more lower.
