Abstract
X-ray diagnostic tests are important for public health. Such tests may involve significant patient irradiation and may be the population's largest radiation source. X-ray mammograms show different female lesions using ionizing radiation. The result is exposure to a small amount of increased radiation. This study was performed during mammograms to determine the average absorbed dose of x-rays and factors influencing the breast's median glandular dose (MGD). The study was conducted in Khartoum, Sudan, mammography patients. Sample size was 300 patients with different disease types. This study was in two Khartoum Hospitals. This study evaluated Robson's Mean Glandular Dose (MGD) and additional mammographic dance tests. Patient age, breast thickness, tube filter and exposure factors (mAs and kVp) were study parameters. Calculated MGD results show that patient exposure was significantly lower than standard IAEA dose. For Craniocaudal and Oblique projections, the average MGD values were 1.54 + 0.17 (p<.05) and 1.58 + 0.22 (p<0.05). This study documented patient characteristics and radiation exposure factors. For international agencies (IAEA, NCRP and ACR), these results should be less than the standard dose.
