Technical performances of two optically stimulated luminescence readers including, a microStar reader and an Auto 200 reader both manufactured by Landauer, Inc. were studied by the National Radiation Protection Agency Dosimetry Laboratory using manufacturer and International Electrotechnical Commission requirements. The two reader tools demonstrated satisfactory results as they met all the requirements. The two readers showed similar performance for the overall uncertainty and the Coefficient of Variation tests. The microStar reader showed better performances for the linearity and quality control tests, whereas the Auto 200 reader has a lower limit of detection. Moreover, an average shift of 0.08 mSv exists when measuring the doses with the two readers.

The performance of an optically stimulated luminescent (OSL) passive dosimetry system named MicroStar reader manufactured by Landauer Inc and acquired in 2011 is assessed in this study. The assessment carried out is based on the results of the intercomparison (IC) exercises organised by the International Atomic Energy Agency in 2013 and 2021. The IC results show that this OSL reader can maintain good performance after long-term usage provided adequate maintenance and calibration operations are carried out.

Stereotactic Ablative Radiotherapy (SABR) remains one of the preferred treatment techniques for early-stage cancer. It can be extended to more treatment locales involving the sternum, scapula and spine. This work investigates SABR checks using Alanine and nanoDot dosimeter for three treatment sites, including sternum, spine and scapula.

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 dose linearity, reader accuracy, reproducibility, batch homogeneity, energy dependence and signal stability, were explored. The suitability of the nanoDot™ dosemeters was evaluated by measuring the depth dose curve, in vivo dose measurement and image perturbation.
