title: [Dosimetry with thermoluminescence during mammography].
abstract: 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.
