摘要

The purpose of this work was to implement the European Protocol on Dosimetry in Mammography is Sweden. The standard average glandular dose, AGD, was measured on 32 mammography units in southern Sweden, according tio the European protocol as well as to the Nordic protocol. The most important difference is that the European protocol evaluates the half value layer, HVL, of the X ray beam with the ecompression paddle present, while it is absent in the Nordic protocol. This results in considerably higher HVL values from the European protocol and thus to higher conversion factors for the calculation of the standard AGD.
