Abstract
The area ratio (R) of low (25 - 180 oC) and high (180 - 300 oC) temperature glow peaks in CaSO4:Na,Dy has been used to estimate the elapsed time (t) after an acute exposure to gamma rays. The magnitude of radiation exposure could be obtained from the high temperature TL peak with a maximum uncertainty of -20%. Apart from t, the value of R is influenced by storage temperature, radiation exposure and its LET. The t values can be estimated with a maximum error of ± 100% if the storage temperature and the type of radiation are known.
