Exposure of the breast, corresponding radiation risks and radiation protection for women, undergoing conventional X-ray examinations

The purpose of this work is to investigative radiation protection of the female breast in different X-ray examinations, including radiography. It is actual, because Publication ICRP №103 takes female breast to maximum irradiating organs. Analysed: risk of ionizing radiation, FB cancer, volume and dynamics X-ray examinations, female breast organ dose and effective dose. In conformity with data of Publication ICRP №103, effective dose of patients at mammography increased in 2,4 time and reach 0,48 mSv for examination as compared with 0,20 mSv with data of Publication ICRP №60. It is shown, that among different cancer, female breast cancer takes first place and constancy increased. Quantity of mammograms for 10 years increased in 2 time and collective dose increased in 2 times at last 7 years. Female breast average organ dose in mammography is 0,96 mGy and effective dose 0,05 mSv. It is only a part of summary irradiation from all X-ray examinations. The average mean value female breast organ dose of all radiography is 1,84 mGy (anterio-posterior projection – 1,57 mGy, lateral – 2,91 mGy) and effective dose – 0,25 mSv (anterioposterior – 0,26 mSv, lateral – 0,17 mSv). Considerable female breast irradiation is caused by X-ray spine examinations (thorax and lumbar). It is necessary to ensure radiation protection of female breast in diagnostic radiology, including quality control and optimization. Also need to shut female breast by X-ray protection apron, particularly in the lateral projection.
