Characterisation and evaluation of Al2O3:C-based optically stimulated luminescent dosemeter system for diagnostic X-rays: Personal and in vivo dosimetry
This study characterises and evaluates an Al2O3:C-based optically stimulated luminescent dosemeter (OSLD) system, commercially known as the nanoDot™ dosemeter and the InLight® microStar reader, for personal and in vivo dose measurements in diagnostic radiology. The system characteristics, such as do...
