OBTAINING A SYSTEM OF DOSIMETRY. Progress Report No. 8 for November 28, 1957-January 27, 1958
Progress is reported in the evaluation of integrating dosimetry systems. The results indicate that two dosimetry systems, ceric sulfate and glass, were the best available for use with cobalt-60 gamma radiation in the dosage range of interest for food sterilization. Additional data were obtained on the response and fuding of silver-activated phosphate glass dosimeters. Two models of an electron beani secondary emission current monitor were tested. The response of the devices was found to be linear and independcnt of electron beam energy in the range 10 to 30 Mev. Saturation was found to be possible at chamber voltages less than 100 volts for instantaneous current densities as high as 150 ma/ cm/sup 2/. These characteristics indicate that the device provides a straightforward method of monitoring the current in high-cnorgy electron beams. (C.H.)
