Individual monitoring with BeOSL dosemeters: New dosemeters for extremity and area dosimetry.
Radiat. Meas. 132:106258 (2020)
To extend the applications of BeOSL technology beyond whole body dosimetry, three new dosemeters were developed: an eye lens dosemeter and a finger ring dosemeter using a single BeOSL detector element and a two-element area dosemeter for work place monitoring. This work describes the new dosemeters, provides data from the radiological characterization of the dosemeters according to IEC 62387 and addresses the issue of measurement uncertainty and detection limits achievable with the BeOSL systems. The response of the new extremity dosemeters in terms of H-p(3) and H-p(0,07) with respect to photon energy and angle of incidence fulfills the IEC 62387 requirements. The area dosemeter fulfills the IEC requirements for workplace monitoring but not the more stringent requirements for environmental dosimetry, due to an under-response for angles of incidence larger than 60 degrees. The results of an uncertainty analysis for the dose evaluation of single element dosemeters show that detection limits in the range of 26 mu Sv-43 mu Sv can be achieved if dedicated background dosemeters are used.
