A dosimetry study using lithium fluoride TL dosimeters was carried out during mammography in 34 patients in order to evaluate in vivo the dose of mammography rays received by these patients. The measures are made for one breast only, using two views: cranio-caudal and medio-lateral views with compression. The results show that skin entrance doses are going from 0.20 to 1.67 cGy in cranio-caudal view and from 0.15 to 1.75 cGy in medio-lateral view. The skin exit doses are from 0.001 to 0.21 cGy in cranio-caudal view and from 0.001 to 0.13 cGy in medio-lateral view. The midplane doses estimated from the skin entrance dose and the graph of the deep yield are from 0.07 to 0.48 cGy. These doses are comparable with those founded by other authors, and though maximum, they stay very low. This is important for detect the breast cancer in order to reduce radiation risks.
为了在体内评估34名患者在乳房X线摄影检查期间所接受的乳房X线摄影射线剂量，开展了一项使用氟化锂热释光剂量计的剂量测定研究。仅对一侧乳房进行测量，采用两种体位：头尾位和内外侧位并施加压迫。结果显示，头尾位的皮肤入射剂量为0.20至1.67 cGy，内外侧位为0.15至1.75 cGy。头尾位的皮肤出射剂量为0.001至0.21 cGy，内外侧位为0.001至0.13 cGy。根据皮肤入射剂量和深部剂量产额曲线估算的中间平面剂量为0.07至0.48 cGy。这些剂量与其他作者所测得的剂量相当，虽然是最大值，但仍然非常低。这对于乳腺癌检测以降低辐射风险而言很重要。
