Fiber-Optic Cerenkov Radiation Sensor for Proton Therapy Dosimetry
Optics Express, 2012 In proton therapy dosimetry, a fiber-optic radiation sensor incorporating a scintillator must undergo complicated correction processes due to the quenching effect of the scintillator. To overcome the drawbacks of the fiber-optic radiation sensor, we proposed an innovative method using the Cerenkov radiation generated in plastic optical fibers.

Feasibility of Fiber-Optic Radiation Sensor Using Cerenkov Effect for Detecting Thermal Neutrons
Optics Express, 2013 In this research, we propose a novel method for detecting thermal neutrons with a fiber-optic radiation sensor using the Cerenkov effect. We fabricate a fiber-optic radiation sensor that detects thermal neutrons with a Gd-foil, a rutile crystal, and a plastic optical fiber. The relationship between the fluxes of electrons inducing Cerenkov radiation in

Distributed fiber optic radiation sensors [PDF]
Safety of Nuclear Waste Disposal, 2021 The international research efforts focused on the development of radiation sensors based on optic fibers have their origins in the 1970s (Evans et al., 1978). Generally, the lightweight fiber optic sensors are immune to electromagnetic field interference and high voltages making them deployable in harsh environments at hard to reach areas where ...
