Abstract: Objective: To establish dose reference levels for the adult abdominal CT scan modality at MTRH, Eldoret Hospital, St. Luke’s Hospital and Medi heal Hospital in reference to the international DRLs. Methods: A retrospective study, reviewed CT scans of 700 adult patients conducted in the 4 health institutions from Uasin Gishu healthcare system in a period of 1 year in the year 2021 using systematic and consecutive sampling. The Volumetric CT-dose index (CTDIvol) and dose length product (DLP) length from the various adult CT abdominal scans were obtained. Results: The mean CTDIvol was 8.1 (22.2) and the mean DLP values was 1699.1 (1053.1). Comparison by scan model it was observed that the median for the Total DLP and for the CTDIvol significantly differed by the model with the median for the Neusoft model being highest at 2538 mGy.cm and 10.3mGy respectively while those for the Siemens were the lowest for the two markers at 1318.5 mGy.cm for the DLP and 5.39mGy respectively. These findings were statistically significant with a p value of
