Absorbed energy in thermoluminescent powder embedded in a binder

The energy absorbed in the grains of a thermoluminescent powder embedded in a solid binder was evluated. The calculations were made with the Howarth method and by means of a computer. The influence of the various physical, geometric parameters (in particular the grain diameter) on which the absorbed energy depends, has been shown. The following cases evaluated : CaF2 and lithium borate powders embedded in silicone rubber or telfon, in various percentages. The calculations referred to CaF2 powder embedded in silicone rubberwere experim entally controlled too.
