A Correlation: TL response of synthetic fused quartz with 60 Co gamma (high dose) source and 90Sr/ 90 Y Beta (low dose) source

Abstract

The correlation between TL response of synthetic fused quartz with ⁶⁰Co gamma source and ⁹⁰Sr/⁹⁰Y beta source are discussed. In the present study the thermo luminescence response of two batches of synthetic fused quartz irradiated simultaneously with gamma and beta rays were obtained with Thermo Electron Corporation manual TLD Reader Model number 3500 TLD reader. The result revealed that this phosphor tends to exhibit a very close TL glow shapes for different test doses using the two irradiation sources. There seems to be a significant relationship in the dose response and the fading of the phosphor with the different irradiation sources. The seeming distinct properties of this phosphor with the two types of irradiators suggest the suitability of this material for mixed radiation dosimetry.
