Abstract

The OSL decay curve of alumina-rich components from personal objects and the preheat treatment is investigated. An early observation showed that the dose increases with increasing OSL integration time. It is shown that this is caused by an unresolved low temperature TL peak (140°C) contributing to the OSL, but with a lower thermal stability than the main contributing TL peak at 190°C.
