Radiation resistance for several fiber samples is explored, with emphasis on variations in draw temperatures for both low- and high-OH preforms. For a given preform type, draw temperature had minimal effect on radiation resistance for transient conditions below 10 over the -7 power s. Dosimetry techniques were intercompared for pulsed electron accelerators. A high purity, high-OH content, fiber was tested for radiation response to determine transient attenuation for 4 ns to 10 over the 4 power s.
