    Radiation dose levels for adult most common Computed Tomography (CT) examinations namely brain, chest and abdomen CT scans were studied. Radiation dose reports, scan parameters and demographic information were surveyed for a period of three - months. Ethical approvals were obtained from the research ethics committee of Ministry of Health and the studied centers. Data were randomly collected using a simple random technique from 131 adult patients with weights 70 ± 3kg. The General Electric 8 and 16-slice and 160-slice Toshiba CT scanners were used in the study. The data were analyzed using SPSS (version 20.0 Chicago) statistical software. The results indicated that the CTDIw and DLP values were (62.5 mGy and 2946mGy*cm), (9.9mGy and 663.3 mGy*cm) and (13.5 mGy and 1397 mGy*cm) for brain CT, chest CT and abdominal CT scans respectively. The study shows that the CTDIw values are relatively similar to those reported in established work by the European Commission. However, the DLP values are comparably higher than those of the European Commission. This revealed that there is need for robust and sustained optimization program so as to reduce patient doses without affecting diagnostic image quality.
