A review of optical fibre radiation dosimeters

Abstract

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.

Radiation dosimetry using optically stimulated luminescence in fluoride phosphate optical fibres

“…Optical fibre dosimetry has been studied as a method of monitoring radiation for medical invivo applications and distributed measurements in environments of high dose-rate [1,2]. Optical fibres provide several advantages in the field of dosimetry.…”

“…The first employs an extrinsic architecture, where the radiation-sensing component is spliced or coupled to an optical fibre [1,2]. In such cases the fibre acts only as a waveguiding component to carry an optical signal from the sensing component to a detector.…”

Bragg wavelength shift for irradiated polymer fiber Bragg grating

“…They found that the oxygen deficient centers in the amorphous silica acting as carrier traps during irradiation. Whereas, O'Keeffe et al [17] studied the effect of gamma rays of doses range from 100 to 3 KGy on the PMMA optical fiber. They found that the optical fiber gave a real-time information about the radiation doses.…”

Optical Fibers and Optical Fiber Sensors Used in Radiation Monitoring

“…The possibility of small, simple interfaces along with lightweight fiber technology results in very appealing sensors. Optical fiber sensors have also been shown to have high sensitivity, large dynamic range along with high resolutions (O'Keeffe, 2008).…”
