Abstract
The thermoluminescence (TL) properties of raw and annealed feldspar have be en studied for their use in gamma dosimetry. The raw gamma exposed feldspar shows glow peaks at 120 degrees C and 319 degrees C. Gamma dose beyond 500 cGy can be measured without any significant fading even after 40 days of t ermination of exposure. The annealed feldspar shows a glow peak at 120 degr ees C after gamma exposure. This peak can be used to measure gamma doses be yond 25 cGy when the TL is measured after 24 h from termination of exposure .
