A new series of dosimetric devices, based on the optically stimulated luminescence (OSL) of BeO, is presented. The dosimetric properties of BeO and the use of OSL are favorable with a linear range at least up to 10 Sv, near tissue energy response, and because of the use of OSL as a measurement technique, the dose information can be re-read. The myOSLraser device combines measurement and zeroing equipment in a single unit and is thus cost and time efficient. The manual reader for single myOSLdosimeters, consisting of two BeO-elements for Hp(0.07) and Hp(10), can be expanded by myOSLautomation, which allows a fully automated analysis of 200 dosimeters. The system exceeds the requirements of EN/IEC 62387. A truly portable handheld device (myOSLchip) allows the manual operation of single element dosimeters, e.g. in phantoms. A simple method is proposed to use the OSL decay signal for the normalization of equipment and bringing into line the sensitivity between instruments.
