This study was done in two hospitals in Sudan in Khartoum state to assess organ dose to patient undergoing skull x-ray. The CAL-Dose software was used for calculations of entrance surface air kerma (ESAK) and organs doses by entering the patient information and parameters (age, ID, sex, name, and field of position, kV, mAs, and machine type). Variation was found in values of the entrance surface air kerma ESAK and organ dose at each hospital. These variations were due to different settings of the exposure factors to each patient. When comparing the values of ESAK to each hospital with the international diagnostic reference level (DRL) it was found that they were lower than DRLs, and it was found that the value of hospital 1was greater than that of hospital 2, and the eyes received higher organ radiation dose as compared with (oral mucosa, salivary gland, brain doses) because their radio-sensitivity is higher.
