Abstract
Radiation doses to patients resulting from chest X-ray examinations were evaluated in four medical centers in the West Bank
and East Jerusalem—Palestine. Absorbed organ and effective doses were calculated for a total of 428 adult male and female
patients by using commercially available Monte Carlo based softwares; CALDOSE-X5 and PCXMC-2.0, and hermaphrodite
mathematical adult phantoms. Patients were selected randomly from medical records in the time period from November 2014
to February 2015. A database of surveyed patients and exposure factors has been established and includes: patient’s height,
weight, age, gender, X-ray tube voltage, electric current (mAs), examination projection (anterior posterior (AP), posterior
anterior (PA), lateral), X-ray tube filtration thickness in each X-ray equipment, anode angle, focus to skin distance and X-ray
beam size. The average absorbed doses in the whole body from different projections were: 0.06, 0.07 and 0.11 mGy from AP,
PA and lateral projections, respectively. The average effective dose for all surveyed patients was 0.14 mSv for all chest X-ray
examinations and projections in the four investigated medical centers. The effect of projection geometry was also investigated.
The average effective doses for AP, PA and lateral projections were 0.14, 0.07 and 0.22 mSv, respectively. The collective
effective dose estimated for the exposed population was ~60 man-mSv.
