“…(64) More recently, HOLZAPFEL,(~~) who investigated the TSEE of a pure, unfired Be0 (E. Merck ''hochrein") suggested adsorbed oxygen as surface traps, and Be vacancies which are occupied by one or two electrons as volume traps. Fading experiments at ORXL(42) support his hypothesis that the lower peak at -240°C consists of two super-imposed maxima of which the lower is due to adsorbed oxygen.…”

In order to obtain more information on the relation between thermally stimulated exoelectron emission (TSEE), thennoluminescence (TL), and the impurity content in different TL grade, analytical and technical grade samples of LiF and BeO, a number of experiments have been carried out, in particular (a) semi-quantitative spectroanalysis and mass spectrography, (b) an investigation of the TL sensitivities and glow curves for different dose levels and LET of the radiation, arid (c) studies on ?'SEE sensitivity and peak locations (including their dependence on LET and heating rate).Sintered B e 0 samples exhibit the highest TSEE sensitivity, in particular after their work function has been reduced by the partial diffusion of inert metals into the surface. The results are discussed on the basis of the existing information on TSEE and TL in LiF and BeO.

“…Recently, a new OSL dosimetry system was developed in Germany based on Thermolox™ 995 BeO material previously investigated as TL and TSEE detector [47][48][49][50]. Commercial grade ceramic chips were used as an OSL phosphor emitting UV luminescence under blue light stimulation [14,[51][52][53][54].…”

The optically stimulated luminescence (OSL) technique has already become a successful commercial tool in personal radiation dosimetry, medical dosimetry, diagnostic imaging, geological and archeological dating. This review briefly describes the history and fundamental principles of OSL materials, methods and instrumentation. The advantages of OSL technology and instrumentation in comparison with thermoluminescent technique are analyzed. Progress in material and detector engineering has allowed new and promising developments regarding OSL applications in the medical field. Special attention is dedicated to Al 2 O 3 :C as a material of choice for many dosimetric applications. Different aspects of OSL theory, materials optical and dosimetric properties, instrumentation, and data processing algorithms are described. The next technological breakthrough was done with Fluorescent Nuclear Track Detectors (FNTD) that have some important advantages in measuring fast neutron and high energy heavy charge particles that have become the latest tool in radiation therapy. New Mg-doped aluminum oxide crystals and novel type of imaging instrumentation for FNTD technology are discussed with regard to application in mixed neutron-gamma fields, medical dosimetry and radiobiological research.

“…The energy and intensity of optically stimulating light affect OSL emission. Albrecht and Mandeville (1956) showed that BeO samples that are irradiated with x-rays emit UV-light (310-370 nm) under stimulation by UV-light (410 nm). The advances in Contents lists available at ScienceDirect journal homepage: www.elsevier.com/locate/apradiso OSL dosimeters were accelerated after the study by Akselrod and Mckeever (1999).…”
