Feital José Ubiratan Delgado Ricardo Tadeu Lopes Biología Mammography Traceability Glandular dose National code of practice The breast is one of the major organs in terms of in terms of biological effects according to the International Commission on Radiological Protection (ICRP), and therefore one of the highest weighting factors for the estimation of risk of cancer induction due to practice of Mammography. In Brazil the Radiodiagnostic Technician Regulation Medical and Dental (National Code 453, 1998) does not contemplate acceptable levels to Mean Glandular Dose (MGD), nor about the actions of the regulatory body regarding exposures in different thicknesses of compression and breast glandularity in the implementation of mammographic screening programs. The objective of this paper is to present and compare with other studies, the results of measurements of MGD in a breast phantom. The adequate traceability was showed in measurements of these quantities, and 56 results in 3 different mammographers to the MGD were compared with the acceptable levels of IAEA, obtaining a 97% index. In most of these comparisons and within each effective depth measurements of the MGD, achieved 75% accuracy in relation to acceptable content. A statistical test was applied in four samples involving the two sets target-used filter. From these results, are suggested regulatory actions to meet acceptable levels of MGD. 2019 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280899004 en http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.3 Vol.7 |
