The purpose of this study is to determine diagnostic reference level for children through entrance surface dose (ESD) calculations. Radiation doses received by 790 pediatrics patients, during routine x-ray examination, at departments of diagnostic radiology in five hospitals in Khartoum state, were calculated. Patients are classified into four age groups, 0-> 1year, 1-> 5 years, 5-> 10 years and 10->15 years old. The X-ray tube output for each equipment was measured using calibrated ionization chamber (RAD – Check Plus model 06-526). Variation was found in values of ESD from hospital to another, these variations were due to difference in settings of the exposure factors to each patient, also to the difference of output of machines. Results were compared with the international diagnostic reference levels and they were greater than the international diagnostic reference levels.
