Aims and objectives
♦The chronic exposure to low-dose ionizing radiation has raised serious concerns regarding the potential development of occupational cataract and eye lens opacities [1-3],
as well as the development of brain disorders [4,5].
♦Based on recent epidemiological studies [6,7],
the International Commission of Radiological Protection (ICRP) revised the annual occupational equivalent dose for the eye lens to 20 mSv and the threshold for cataract formation to 0.5 Gy .
Depending on the workload,
Methods and materials
♦ Study period: November 2017 - February 2018
♦Study department: 2 nd Department of Radiology,
Attikon University Hospital,
♦ Study system: Flat-panel fluoroscopy system
♦ Number of interventional radiology procedures studied: 98 lower-limb percutaneous transluminal angioplasties (PTA LL): 70 embolizations/chemoembolizations: 15 vertebroplasties: 13 ♦ Number of IR groups involved: 2 (see Tables 1 and 2)
♦Radiation dose measurements: LiF:Mg,
Ti thermoluminescent dosimeters...
The results of the current study are presented on Figures 2-8.
♦This work studied crucial factors affecting cephalic doses to IRs such as the type of the procedure the standing position of IR the IR’s experience the use of radiation protection tools ♦Doses to the left head side were significantly higher than corresponding ones to the right side (p=0.005),
reflecting IR’s position (Figures 2-4) ♦The highest dose per procedure was recorded to the left eye lens in vertebroplasties (1762 μSv) (Figure 4) ♦Data presented in Figure 5 suggest a more effective...
