Abstract

A method of radiation dosimetry based upon the radiophotoluminescence (RPL) of synthetic diamond crystals is presented. When the RPL is generated by a stimulation wavelength of 296 nm a linear response vs radiation dose of up to 20 kGy can be obtained with selected crystals. The response is very dependent on the chemistry of the synthesized specimen.
