The spread in measured equivalent doses (Ds) for each sample was generally consistent with the OSL signals being fully reset before deposition.
The OSL ages generally increased with depth and indicated a 24-ka sedimentary record for the upper 50 m of the core.
It is a major step up from the DOS version, basically a database-centered application, and virtually free of restrictions on size or contents.
While a simple 386SX system (if you can still find one!
The OSL dosimeter provides a new degree of sensitivity by giving an accurate reading as low as 1 mrem for x-ray and gamma ray photons with energies ranging from 5 ke V to greater than 40 Me V.
The OSL dosimeter's maximum equivalent dose measurement for x-ray and gamma ray photons is 1000 rem.
This system can be used for standard TL and OSL measurements in Geo-/Archaeochronometry, mineralogical research, solid state and retrospective dosimetry, radiation control and material sciences.
8-10 weeks) with routine precision: £315 ( VAT) per sample for batches of up to 9 samples.
A Windows version, First Light, is to released in January 2001, and is a general purpose application for TL, OSL, and, shortly, ESR.
The photons are detected using a photomultiplier tube.
The signal from the tube is then used to calculate the dose that the material had absorbed.
lexsyg smart is a low cost luminescence reader for standard routine measurements of luminescence using TL and OSL (thermal and optical stimulation).
Based on the success and experience of our fully automated lexsyg research TL OSL reader system, the lexsyg smart offers all routine functions necessary for fast and standard measurements.
