Gamma radiation resistant Fabry–Perot fiber optic sensors
Review of Scientific Instruments, 2002The Nuclear Regulatory Commission (NRC) in 1998 completed a study of emerging technologies that could be applicable to measurement systems in nuclear power plants [H. M. Hashemian et al., “Advanced Instrumentation and Maintenance Technologies for Nuclear Power Plants,” NUREG/CR-5501 (1998)].

Amplitude-time characteristics of a fiber optic ionizing radiation sensor
SPIE Proceedings, 1999In work the formulas for calculation of the amplitude-time characteristics of a Cherenkov fiber-optic ionizing radiation sensor are given. The results of the mathematical modeling which has been carried out on these formulas, coincide qualitatively with experimental data.

Characterization of fiber optic Cerenkov radiation sensor for detecting neutrons
SPIE Proceedings, 2013Cerenkov radiation can be observed easily as a shimmer of blue light from the water in boiling- and pressurized-water reactors, or spent fuel storage pools. In this research, we fabricated the fiber-optic Cerenkov radiation sensor using a Gdfoil, rutile crystal and optical fiber for detecting neutrons.

Determination of the energy of ionizing radiation using fiber-optic sensors
12th International Conference on Optical Fiber Sensors, 1997During radiation therapy the dose distribution in the patients body depends on type and energy of the applied ionizing radiation. Therefore the determination of the energy or energy distribution of this radiation is important with regard to the quality assurance in radiation therapy. On the basis of an attenuation based fiber-optic dosimeter system for

Study of a compact radiation source for fiber-optic interferometric phase sensors
Journal of Optical Technology, 2015This paper discusses the optical and electrical characteristics of the RayCan RC32 laser diode, with a vertical cavity that emits at a wavelength of 1550 nm, as a function of various operating regimes. The possibility of using laser diodes with a vertical cavity in fiber-optic interferometric phase sensors is considered.

Raman distributed temperature sensor (RDTS) measurements were performed during γ-radiation on three different classes of standard multimode fibers (pure, Ge-doped and F-doped). The sensor response is affected by the radiation induced attenuation phenomena leading to errors in the temperature measurements. The amplitude of this error strongly depends on

Radioactivity measurement of radioactive contaminated soil by using a fiber-optic radiation sensor
Journal of the Korean Physical Society, 2016A fiber-optic radiation sensor (FORS) was developed to measure the gamma radiation from radioactive contaminated soil. The FORS was fabricated using an inorganic scintillator (Lu,Y)2SiO5:Ce (LYSO:Ce), a mixture of epoxy resin and hardener, aluminum foil, and a plastic optical fiber.

Journal of the Korean Physical Society, 2013
In this study, we developed and characterized an integrated fiber-optic sensor for the remote detection of alpha radiation emitted from radioactive contamination in areas relatively inaccessible by radiation workers. The fiber-optic sensor consisted of an epoxy-resin supporter and a sensing probe attached to it.
