OSL detectors can be stimulated numerous times to confirm the validity of a radiation dose measurement. A full reanalysis is automatically performed for every dosimeter with an assessed dose in excess of 5 mSv.

The analysis of the Imaging component renders unique filter patterns that provide qualitative information about the conditions during exposure. Imaging to identify static, dynamic, or contamination conditions is automatically performed for all beta and low-energy photon measurements yielding a dose in excess of 5 mSv. Imaging capabilities are inconclusive at energies exceeding 150 keV.
A static exposure image indicates the dosimeter was still with no movement at the time of exposure. This is verified by the distinct grid patterns in the filter pack imaging area. A static exposure implies that the dosimeter may not have been worn at the time of exposure, and an accidental exposure may have occurred.
A dynamic exposure image indicates the dosimeter was moving at the time of exposure. This is verified by the blurred grid patterns in the filter pack imaging area. A dynamic exposure implies that the dosimeter was worn at the time of exposure, and the reported dose is valid.
Reanalysis or imaging at doses less than 5 mSv can be requested to our Customer Service. Imaging is not available for doses less than 0.5 mSv.
