Thermoluminescence of Uranyl Salts Under Mechano-destruction

Abstract

The thermoluminescence of the salts UO2(NO3)2·6H2O and UO2(ClO4)2·6H2O that have been previously treated mechanically at 77K was studied. A maximum was observed in thermoluminescence curve at 80-90K. The thermoluminescence peak intensity depends on duration of mechanical treatment at 77K. The trap depth of glow centers has been determined using experimental thermoluminescence curves. The calculated activation energy ETL and frequency factor p0 were 0.21eV and 1010 s–1, respectively
