Effects of Radiation on Vidicon Performance

A commercial one-inch vidicon was exposed to a total radiation dosage of approximately 1015 NVT in the Brookhaven National Laboratories Nuclear Pile Reactor. Quantitative tests were devised for measuring tube aperture response, signal, noise, and photoconductor "dark" current. No measurable degradation of performance occurred, except for decrease in signal output, which was attributed to radiation browning of the vidicon glass faceplate.
