Mechanoluminescence of <img src='/image/spc_char/gamma.gif' border=0>-irradiated salt

Abstract

The dependence of mechanoluminescence (ML) intensity on <img src='/image/spc_char/gamma.gif' border=0>-dose of irradiated salt has been studied. It is found that initially the ML intensity increases with increasing

<img src='/image/spc_char/gamma.gif' border=0>-dose given to the sample, attains an optimum value around 3×10³ Gy then decreases with further increase in

<img src='/image/spc_char/gamma.gif' border=0>-dose. The spectroscopic study of ML and the effect of optical bleaching and storage (fading) on ML intensity have also been investigated to understand the mechanism of ML excitation in household salt. The radiation-induced changes in food material might also be analyzed by studying their ML properties.
