Assessment of Skin Effective Dose and Radiation Risk for Chest, Abdomen and Pelvic During Conventional X-Ray Examinations

Taha.T.M

Abstract: Assessment of effective skin doses and radiation risk for patients resulted from conventional x-ray examinations should be made as a means for minimizing the probability of stochastic radiation effect. Entrance skin dose was determined indirectly via generating X-ray dose output factors, back scatter factor, focus to skin distance, mAs and applied tube kV in mathematical model. The effective skin dose is calculated based on tissue weighting factor for each projection. The mean and standard deviation for effective skin doses for chest PA, abdomen, pelvic AP were 13.8 ± 0.4, 25 ± 14, 54.1 ± 3.3 µSv respectively. The effective skin dose calculation was giving minimum stochastic radiation effect rather than effective dose.
