This study designed to evaluate the patient doses and the radiation related factor, and helps to improve Occupational awareness to ionizing radiation hazard from CT procedures and the impotent of radiation protection protocols to achieve ALARA principle. Four CT machines were used to collect data in Khartoum state, and a quality control tests were performed to the machines prior any data collection. Comparing the demographic and radiographic information from CT brain among male and female for age and BMI the age data shows the males was older than female and the body mass index data it’s almost similar for both gender. The radiographic data the mA was higher for female than male while the DLP CTDIvol and effective dose was higher for male. Comparing the demographic and radiographic information from CT chest among male and female we found that the Ma for female was higher than male, while the dose length product and computed tomography dose index per volume was higher for male, the effective dose the male was higher than that from female. Comparing the dose parameters among the two exams for all hospitals for brain the CTDIvol, DLP and ED was 77.44 ± 30.51, 2142.3 ± 3309.17 and 4.49 ± 6.94 respectively, while for chest was 40.47 ± 38.58, 963.23 ± 624.77 and 13.48 ± 8.74. And when compared with diagnostic reference level and other countries found that the CTDIvol was lowest at present study between all studies except the study from UK 2013. The main dose variations in the same CT unit could be attributed to the different techniques, which justify the important of use radiation dose optimization technique and technologists training. Dose reduction strategies must be well understood and properly used.
