“…Reference [2] discusses some early studies on this topic in detail and includes halides (KCl, KBr, NaCl, RbI, CaF 2 , and BaFX with X = Br, Cl, I), sulfates (MgSO 4 and CaSO 4 ), sulfides (AS, with S = Mg, Sr, Ca, and Ba), and oxides (BeO and fused quartz). Except for BeO [7][8][9], these materials have not yet been adopted in dosimetry because they possess one or more undesirable features such as fading, low sensitivity to radiation, high effective atomic number, or even self-dose [10][11][12][13]. But even BeO has disadvantages: it is toxic in the powder form, so it must be used in the single ceramic form [14].…”

“…In this work, a blue LED CREE XT-E Royal blue is used as stimulation source. The peak wavelength of this LED is around 450 nm while the wavelength of the luminescence light is below 370 nm [5]. A combination of different filters is used to allow mainly luminescence light to pass on to the sensor.…”

“…de) For OSL, there are several possible luminophors, like CaF2 [1], BeO [2] or Al2O3 [3]. One suitable luminophore for OSL in personal dosimetry is beryllium oxide (BeO) because of its near tissue equivalent effective atomic number of 7,1 [4] [5]. The luminescence of BeO in the UV region below 370 nm, can be effectively stimulated by broadband blue light.…”

Single photon detection applied to optically stimulated luminescence (OSL) dosimetry is a promising approach due to the low level of luminescence light and the known statistical behavior of single photon events. Time resolved detection allows to apply a variety of different and independent data analysis methods. Furthermore, using amplitude modulated stimulation impresses time-and frequency information into the OSL light and therefore allows for additional means of analysis. Considering the impressed frequency information, data analysis by using Fourier transform algorithms or other digital filters can be used for separating the OSL signal from unwanted light or events generated by other phenomena. This potentially lowers the detection limits of low dose measurements and might improve the reproducibility and stability of obtained data. In this work, an OSL system based on a single photon detector, a fast and accurate stimulation unit and an FPGA is presented. Different analysis algorithms which are applied to the single photon data are discussed.Index Terms beryllium oxide, dosimetry, luminescence, optical stimulated luminescence, single photon detection

“…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.…”

The aim of this study was to assess the effect of eye and testicle shielding on radiation dose to the lens and the testes of patients undergoing CT examinations. Fifty-one male patients underwent CT twice with identical protocols initially without, the second time with protective garments. Doses to the testes and the lenses were recorded with beryllium oxide-based dosimeters. The dose to the testes and lenses from CT exposure was reduced by 96.2% +/- 1.7% and 28.2% +/- 18.5%, when testicle and eye shielding was used, respectively. The effect of the eye shielding on the eye lens dose was found to depend on the x-ray tube position when the eye is primarily exposed during the scan. The maximum eye lens dose reduction achieved was found to be 43.2% +/- 6.5% corresponding to the anterior position of the tube. A significant correlation between the patient's body mass index and dose exposure could not be found. Eye and testicle shields, apart from being inexpensive and easy to use, were proven to be effective in reducing eye lens and testicle radiation dose burden from CT exposures.
