Abstract
The model by McKeever to simulate 'hard-to-bleach' thermoluminescence (TL) peaks is studied. The sensitivity of the model to its parameters is examined. and a wide variety of behaviour is found. The sensitivity of the TL signal and the size of the residual TL level for different sets of parameters are studied. It is observed that the TL sensitivity changes after bleaching and the residual level reached after long ble aching times depends upon the initial radiation dose.
