Symposium on Solid State Conductivity VI. A Note on the Performance of Intracavitary CdS Probes in Supervoltage Therapy

Abstract

A simple photoconductive crystal dosemeter for X- and gamma-rays is described. The induced current is linear with dose rate over the range 0.3 to 150 r/min., and with a crystal cover of 0.8 mm gold the response is sufficiently independent of radiation quality for use in C60 therapy.
