An intelligent microprocessor based TLD reader Model RGD-3 has been de
veloped for routine TLD monitoring and other TL related measurement. W
ith various optimized designs, the TLD reader shows its high versatili
ty, stability, reliability and especially its good environmental adapt
ability in the hot and wet climates. The performance of the RGD-3 TLD
reader meets all the requirements of the International Standard(IEC-16
6:1991) for the ''Thermoluminescence Dosimetry system for Personal & E
nvironmental Monitoring''. Its high benefit-cost ratio affords great p
otential for use especially in developing countries.
