ABSTRACT: During operating of the X-ray machines, if the protection of X-ray rooms
is insufficient, not only the patient but also clinical staffs as well as
public are exposed to high X-ray dosage and they are affected from X-ray
related to the dose level. In the present survey, by testing the radiological
leakage and scatter from X-rays machines in radiology departments of 7 randomly
selected hospitals in Duhok governorate, the effects dose of X-ray to the both
control panel area and the patients waiting or visiting area who are located
near the radiography room, were measured. The dose was recorded for a range of peak
kilovoltage (kVp) and mAs values to find efficiency of shielding materials
(barriers) of radiography rooms for different X-rays level. The measurements were performed at
one meter above the ground surface which was the same height of X-rays tube by
using Gamma Scout dosimeter. From the measurement results, it was seen that the
most hospitals barriers (doors and walls) were not appropriate to the standards except 2 hospitals. The maximum effective doses were measured in
uncontrolled area of Khazer hospital which was 82.48 ± 0.73 mSv·yr-1 that was much more than the reference dose limits and in controlled area of Haval
Banda Zaroka hospital which was 12.98 ± 0.16 mSv·yr-1. In result,
the knowledge about the radiation dose affecting the radiologists and public in
the selected hospitals was obtained, and by informing the radiologists and the
hospitals managements, the necessary regulations would be planned.
