Abstract
The use of solid state detectors for the monitoring of low energy beta rays has been investigated. The solid state detectors utilized were Au-i-n structures using bulk silicon compensated by lithium drift techniques. Their count rate response was compared to the surface absorbed dose rate in polystyrene. This was accomplished through the use of a specially constructed extrapolation chamber. The ratio of the count rate to dose rate was studied as a function of source to detector distance, source size and source thickness. It was found that under many conditions the correlation is sufficiently good that survey meters incorporating such detectors would gave a satisfactory estimate of the skin dose for dose rates exceeding 100 mrad hr.
