Most TLD vs. OSL comparisons rely on outdated detector data or simplified marketing claims.
A new report from RDC President Chris Passmore, CHP, compares modern LiF:Mg,Cu,P TLD and BeO OSL using performance data from RDC’s NVLAP-accredited laboratory (Lab Code 100512-0) – including fade, lower limit of detection, reread performance, and tissue equivalence.
Key takeaways:
• Modern copper-doped lithium fluoride TLD dosimeters perform far differently than legacy TLD-100
• OSL rereads depend heavily on whether the system uses laser or LED stimulation
• LLD claims only matter when tied to actual wear periods
• Tissue equivalence remains one of the most overlooked drivers of dose accuracy
Modern detector performance is more nuanced than most comparisons suggest, and we're sharing valuable technical details to provide greater clarity.
