Abstract: Eu doped strontium aluminate phosphor (SrAl<sub>2</sub>O<sub>4</sub>:Eu) was synthesized by combustion method using urea as a reducer at initiating temperature of 600<span style="font-family:Symbol;mso-ascii-font-family:" times="" new="" roman";="" mso-hansi-font-family:"times="" roman";mso-char-type:symbol;mso-symbol-font-family:="" symbol"="" lang="EN-GB">°C. The mechanoluminescence (ML) of SrAl<sub>2</sub>O<sub>4</sub>:Eu and their suitability for radiation dosimetry have been investigated. Eu doped SrAl<sub>2</sub>O<sub>4</sub> is a good dosimeter having linear response up to about 1180 Gy of <span style="font-family:Symbol;mso-ascii-font-family:" times="" new="" roman";="" mso-hansi-font-family:"times="" roman";mso-char-type:symbol;mso-symbol-font-family:="" symbol"="" lang="EN-GB"><img src='/image/spc_char/gamma2.gif' border=0>-radiation dose.
