The detection and measurement of gamma radiation using materials that are sensitive to such radiation has been a subject of intense investigation. Optical fiber is found to be a good choice in this regard due to greater sensitivity at different dose levels compared to bulk glass dosimeters. The major advantage in using the fiber is that the radiation sensitivity can be adjusted to the dose or dose rate by selecting suitable fiber design, composition and operating wavelength. In addition, the fibers feature a small weight and transverse size, as well as immunity to electromagnetic interferences...
The detection and measurement of gamma radiation using materials that are sensitive to such radiation has been a subject of intense investigation. Optical fiber is found to be a good choice in this regard due to greater sensitivity at different dose levels compared to bulk glass dosimeters. The major advantage in using the fiber is that the radiation sensitivity can be adjusted to the dose or dose rate by selecting suitable fiber design, composition and operating wavelength. In addition, the fibers feature a small weight and transverse size, as well as immunity to electromagnetic interferences. So the dosimeter dimensions can be very small within the area (approx. dia around 3cm ) of wristwatch. The objective of the present thesis work is to develop suitable radiation sensitive optical fibers which can be used as radiation sensor for fiber optic dosimetry application.
