Comparison and development of dose measurements in mammography

Aim of the study

The aim is to study methods used for dosimetry in mammography together with properties and use of different meter types within energy range of mammography and their need for calibrations and proper radiation qualities for calibrations. The project is partly related to the testing of the IAEA diagnostic radiology measurement guide.

Implementation

Meter types used for air kerma measurement in mammography energy range are studied and they are calibrated within the energy range of mammography. Clinical radiation qualities are simulated with rhodium and molybdenum filters. Dose measurements are performed with existing methods and differences and the effect on the outcome is studied. Based on the results, the need for calibrations, radiation qualities and properties of meters are concluded. In addition, the accuracy of methods used for measurements for mammography is estimated.

Dissemination and exploitation of the results

The results are published as a STUK-STO-TR report or as a DOS document, in the publication of testing the IAEA guide, and possibly in an international article or a proceeding.
