The Individual Monitoring Service (IMS) at the Helmholtz Zentrum Miinchen together with Dosimetrics GmbH has developed and characterized a new ring dosemeter for photon radiation for the measurement of H-p(0,07), based on BeOSL technology. This work describes the new finger ring dosemeter and provides data from Monte Carlo simulation and from the radiological characterization of the dosemeters according to IEC 62387, such as the energy and angular response functions of the dosemeter, its dose linearity and the coefficient of variation. Furthermore, the opacity of the dosemeter enclosure and light conditions for packing and unpacking of the detectors are addressed.
