Ring-Dosemeter (OSL)
You can also download all information as a flyer in our download section.
Our OSL ring dosemeter is based on the physical principle of Optically Stimulated Luminescence (OSL). It is a Extremity dosemeter to determine the personal dose equivalent Hp(0,07) due to photon and beta radiation for local skin monitoring.
The dosemeter consists of a numbered dosemeter case (finger ring made of black plastic) and BeO detectors of the type ezClip. The ceramic BeO detectors are harmless to health; there is no risk of inhalation of beryllium particles.
When ionizing radiation hits the detector, energy is stored in the detector’s crystal. When stimulated again with blue light, the stored energy is released in the form of light during the evaluation. The light output measured with photomultipliers is a measure of the dose.
Typically, ring dosemeters are worn on the finger for a wearing period of one month.
