Abstract

In the course of this work, a dosemeter for measurement of ambient dose equivalent H*(10) based on the BeOSL dosimetry system was designed. Calculations of the energy response of the two-element BeOSL personal dosemeter in terms of H*(10) showed that the response does not fulfil the requirements of IEC 62387 Especially, the response for photon energies of 60-100 keV is too low. It is possible to correct this under-response using a BeOSL two-element dosemeter, a linear algorithm and an additional cover for the dosemeter. The Hp(0.07) element is shielded with lead, and with the help of a linear algorithm, corrections of the energy response are possible. So, the national requirements for an H*(10) area dosemeter in Germany can be fulfilled. The requirements of IEC 62387 are fulfilled for angles of radiation incidence from 0° to 60° for a rotation around the vertical and horizontal axis through the dosemeter, whereas for angles of incidence from 75° to 90°, the requirements are only fulfilled for rotation around the vertical axis through both elements.
