Radiation monitor based on wavelength-dependent optical absorption in fused silica optical fibers
A radiation monitor apparatus and method based on wavelength-dependent optical absorption in fused silica optical fibers. The radiation monitor uses the radiation induced optical changes in fused silica optical fibers as a way to quantify and differentiate the large doses of radiation from high energy photons and neutrons as well as providing a method to extend the sensitivity over a large dynamic range of doses from 103 to beyond 106 rads. The radiation monitor enables dynamic monitoring of highly ionizing radiation environments. The radiation monitor reduces sensitivity saturation at high dose levels, provides increased sensitivity over a large dynamic range of doses, and enables differentiation between high energy photon and neutron contributions or poor signal to noise.
