| Zusammenfassung | The effect of different X-ray radiation qualities on the calibration of mammographic dosemeters was investigated within the framework of a EUROMET (European Collaboration in Measurement Standards) project. The calibration coefficients for two ionisation chambers and two semiconductor detectors were established in 13 dosimetry calibration laboratories for radiation qualities used in mammography. They were compared with coefficients for other radiation qualities including those defined in ISO 4037-1 with first half value layers in the mammographic range. The results indicate, that the choice of the radiation quality is not crucial for instruments with a small energy dependence of the response. However, the radiation quality has to be chosen carefully, if instruments with a marked dependence of their response to the radiation energy are calibrated. |
