The microStar reader measures radiation exposure with aluminium oxide detectors (Al2O3:C) read out by Optically Stimulated Luminescence (OSL) technology. It is a portable and lightweight reader, adapted to personal monitoring dosimeters or nanoDots.

The microStar reader can be used anywhere to measure immediate and accurate radiation dose assessments, i.e.: for emergency response, area monitoring, clinical dose assessment, or any
radiation measurement.

As the reading is non-destructive, it allows dose verification and intermittent analysis while maintaining total dose accumulations.

It uses a conventional electrical power source and no other connections. It is therefore a ‘plug-in and operate’ piece of equipment with low maintenance requirements (no heating, no gas).

The reader connects via a USB cable to an external computer that controls the setup, analysis and data recording.

Calibration can be achieved using a set of calibration dosimeters. A diagnostic (80 kVp) set can be supplied on demand.

microStar reader includes operating, analysis and dose calculation algorithm software, laptop computer, carrying case, and a choice of InLight whole body dosimeters or nanoDots for single point measurements.
