Abstract: <span style="font-size:10.0pt;font-family:" times="" new="" roman","serif";="" mso-fareast-font-family:"times="" roman";mso-bidi-font-family:mangal;="" mso-ansi-language:en-us;mso-fareast-language:en-us;mso-bidi-language:hi"="">The mechanoluminescence (ML) of <img src='/image/spc_char/gamma2.gif' border=0>-irradiated coloured powder of KBr:Ce(0.1-10 mol%) phosphor has been studied in the present paper. All samples have been prepared by a wet-chemical method. Single isolated ML glow curve is observed in all samples. The variation of peak ML intensity with gamma rays exposure and different concentration of Ce<sup>3+</sup> doped in KBr:Ce has been studied. The ML intensities are found to be dependant on concentrations of Ce<sup>3+</sup> and gamma radiation dose. The variation of peak ML intensity of KBr:Ce (0.5 mol%) with different gamma dose is found to be as sub-linear up to 1.5 kGy high dose and then after the intensity becomes saturated<i style="mso-bidi-font-style: normal">. </i></span>
