Our BeOSL Dosimeters are personal dosimeters for measuring the Personal Dose Equivalents Hp(10) and Hp(0.07). Sintered ceramic beryllium oxide (BeO) detectors are read out on the principle of optically stimulated luminescence (OSL). BeO is more tissue equivalent than any other commercially used OSL material and therefore ideal for personal dosimetry. Due to its enormous nominal range of use our BeOSL Dosimeters are perfect for almost all applications of whole body dosimetry. We, the manufacturer, deliver calibrated dosimeters only. This is necessary, since all BeO detectors have a different OSL sensitivity.
Here you can get more details and information about the OSL Technology, which is the core of our BeOSL Dosimeters.
The 2-element version is carrying two BeO detectors. For each unit (Hp(10) and Hp(0.07)) only one detector is used, which is possible due to the very good tissue equivalence of the BeO material. The 2-element dosimter shields the Hp(10)-detector with a filter made of Teflon. The cladding is attenuated in the area of the Hp(0.07)-detector to have the least possible shielding against radiation. The protection against mechanical influence and light is still excellent and the small and light-weighted design makes handling and wearing more than easy.
The 4-element version has got two additional detectors that are shielded one with copped and the other one with lead. This gets information over a broad energy range and our algorithm can deliver an even higher accuracy and more information on the irradiated radiation quality.
