Figure 1 from Yasuda & Discher (2020) shows the changes of the cw-OSL curve (solid line) and its deconvoluted short lived component (dotted line) with time. Their OSL intensity ratio allows an estimate of the time since the material was dosed in a radiation accident.

A new method was developed with Freiberg Instruments' lexsyg research luminescence reader for emergency dosimetry. The use of blue stimulated OSL with the dosimetric material Mg2SiO4:Tb (MSO) does not only allow the retrospective measurement of the high dose received during a radiation accident, but can also provide an estimate of the time elapsed since such an event.

Al2O3:C film OSLD can be measured with lexsyg smarts with a precision better than 1% over a 0.2 Gy–10 Gy dose range. Similarly good precision is achievable for other TLD and OSLD materials. The high precision allows application in medical dosimetry…
