“…To separate out the "stem effect" an identical fiber, but without a dosimeter attached, can be placed alongside the fiber with the dosimeter and, by assuming that the "stem effect" is the same in both fibers, the dosimeter RL signal can be obtained by subtraction (Fluehs et al, 1996). Roy et al (1997) designed a remote OSL dosimeter system based on rare earth doped alkaline earth sulphides (e.g. MgS) as the dosimeter material coupled to the end of an optical fiber and stimulated with an infra-red laser diode.…”

“…Alkaline Earth sulfides doped with rare earth ions have also been demonstrated as effective dosimeters, measuring both dose and dose rate, based on OSL. The induced luminescence was determined and demonstrated good linearity for 40 μ Gy to 10 Gy, as can be seen in Figure 3 (Roy et al , 1997).…”

PurposeThe purpose of this paper is to provide a detailed review of radiation dosimetry techniques based on optical fibre dosimeters. It presents a comprehensive bibliography of the current research activities in the area.Design/methodology/approachA range of published work on optical fibre radiation dosimeters are presented, with the merits and limitations discussed. Each radiation dosimetry technique is discussed in turn, providing examples of dosimeters using such techniques reviewed. The main focus is on gamma radiation although other radiation dosimeters are considered.FindingsThis paper provides information on the wide range of research activity into radiation dosimeters. The dose ranges of these dosimeters are presented, along with the advantages and disadvantages of different dosimetry techniques.Originality/valueA comprehensive review of published research in the area of solid radiation dosimetry is presented in this paper. It provides an individual with a review of the various techniques used and most recent research in that field.

“…Concerning radiation detection, these aluminiumcovered sensors can be applied to the monitoring of nuclear installations and particularly in areas out of reach for usual dosemeters. For example, a first generation sensor (2) is routinely inserted in small diameter pipes (typically 10 mm) both for real-time dose measurements and for remote accident detection (radioactive leakages). For radioprotection purposes, a compensation filter package can be developed with the help of the MCNP4b code for the quantity H*(10) (suitable for local dose measurement).…”

“…On this assumption, a first radiation sensor based on rare-earth doped alkaline earth sulphides (AES) such as BaS, MgS or CaS (1) which can be stimulated with an infrared light, coupled with an optical fibre several kilometres long has been achieved. This instrument allows remote dose measurements from about 1 mGy up to several Gy (2) . However, such a device cannot be used for personal dosimetry for several reasons.…”

Optically stimulated luminescence dosimetry (OSL-D) used in conjunction with fibre optics enables a remote measurement of dose, for the purpose of radioprotection in the nuclear industry and in medicine (radiology, radiotherapy). Alumina OSL crystals are used because of their low Z, low fading and optical transparency, which improves the sensitivity. An optoelectronic portable dosemeter has been designed and tested that shows a dose detection of 50 microGy with a 20 metre-long fibre. Following irradiation, all trapped electrons are released under light stimulation while the OSL is integrated to provide dose-equivalent measurements. A compensation technique is designed with the help of the MCNP4b code, so that both angular and photon energy characteristics comply with international standards (CEI 61066) for photon dose equivalent Hp(10). Two sensors are described that allow measurements over a wide solid angle (95% of 4piSr), for photon energies ranging from 15 keV to 3 MeV.
