Read-out System for Glass Dosemeters using Nitrogen Gas Laser

Abstract

  Radiophotoluminescent (RPL) glass dosimetry system has been improved with high progress by using nitrogen gas laser as UV excitation source. This new read-out system provides the discrimination of predose during read-out, no more necessity of glass cleaning before read-out and the automatic repetitive read-outs within a short time. It is possible to measure low dose to 0.03mSv with high accuracy. Now, RPL glass dosimetry system is applicable to individual and environmental monitoring.

  This paper reviews the recent progress in RPL glass dosimetry with respect to read-out systems using nitrogen gas laser.
