The current survey was carried out to detect and identify any radioactivity contamination that might be present in imported second-hand computer monitors in Kosti Dray Port, Sudan. Handheld radiation survey meters, contamination detector and portable gamma-spectrometry were used.The result of this survey has revealed without doubt that the second hand computer monitors did not contain any radioactivity contamination. Because the level of radiation fall within the range of 0.1–0.9 µSv/h with an average value of0.39 ± 0.27 µSv/h. From the obtained results the levels of radiation doses seems to be close the tobackground radiation Hence, the imported second-hand computer monitorsare radiologilly safe and free of any radioactivity contamination. The importance of this work highlights radiation monitoring over the border entrances and ports in Sudan as well as expand the concept of radiation protection and radiation safety culture among the public.
