The emission of light from materials has been a subject of interest since the earliest of times.The association of luminescence,and in particular thermoluminescence (TL),with exposure of a material to the radiations emitted by radioactive salts,was observed by the pioneering research in radioactivity.Both fluorite and calcium fluoride containing manganese were used to detect ionizing radiations.By the 1940s a reasonably clear understanding of the general processes involved in thermoluminescence in crystalline media had been developed as reported by Ginther and Kirk.[1] The borate dosimeters appear to have attractive TL properties compared with the other hosts.[2-6]The borate compounds are stable,easily doped,highly sensitive and close effective atomic number.
