Abstract

Planar waveguides fabricated from triphenylmethane cyanide dyes doped into polymer films, Ag+ diffusion, and GaFChromicTM dosimetry media are evaluated as sensors for real-time radiation monitoring. Filtered 100 keV x rays are used as a model source to compare the attenuation response of these waveguide sensors to ionizing radiation. Preliminary results indicate that all three waveguides demonstrate an increase in sensitivity over conventional dosimetry films using UV-VIS photometric detection. The fabrication, characterization, and response of each sensor are discussed.
