A glass fiber-waveguide dosimeter is described which is particularly well adapted to monitoring radiation over large areas such as cargo holds, waste storage facilities and around reactor and accelerators. The useful range extends below 10 mR to above 10 4R, providing a 10 fold sensitivity increase over conventional glass-block dosimeters. The sensitivity of a lead flint fiber-optic sensing element is discussed and its response due to γ-ray exposure, exposure rate, photon energy, fading and temperature is presented. The response to fast neutrons is compared with that to v rays - Sn/Sγ ~ 0.1 (in rads(tissue)).
