Beryllium oxide as optically stimulated luminescence dosimeter

Measurement of radiation dose with BeO dosimeters using optically stimulated luminescence technique in radiotherapy applications

“…Ceramic beryllium oxide (BeO) has been investigated as a OSL material; however, studies have drawn attention that it can be also used as a TL dosimeter (Sommer and Henniger, 2006;Sommer et al, 2008). BeO is sensitive to ionizing radiation, and has an effective atomic number (Z eff ¼7.2) similar to water (Z eff $ 7.51).…”

Optical Storage Phosphors and Materials for Ionizing Radiation

“…The exact origin of the optically stimulated luminescence of BeO is not clear yet, although a possible link to the thermoluminescence peaks at 220 ºC and 340 ºC has been proposed (Bulur & Göksu, 1998). The linear dose response of the optically stimulated luminescence of BeO was reported from 1 μGy up to a few Gy, covering more than six orders of magnitude (Sommer et al, 2008). In practical applications of BeO in radiation dosimetry, the stimulation is usually realized by employing blue light-emitting diodes and the detection of the light can be easily achieved with a photomultiplier.…”

Dose reduction in computed tomography: the effect of eye and testicle shielding on radiation dose measured in patients with beryllium oxide-based optically stimulated luminescence dosimetry

“…The reader ("BeOmax") has been developed by a group of two of the coauthors (M. S., J.H.) [13][14][15][16]. BeOs feature a linear dose response of between about 5 µGy and up to more than 5 Gy.…”
