The model BPLL readout equipment of lyoluminescence dosimeter has been constructed in our lab. The D. C. current integration method has been employed in the equipment. The model GDB-52 photomultiplier has been selected as a light detector, the model NWF-02 A weak current amplifier and a voltage-frequency converter have been used. The sensitivity of the equipment can be regulated and its stability in 8 hours is satisfactory for dose measurement, the standard deviation of the mean of 48 measured values is ±0.4%. The glutamine lyoluminescence dosimetric characteristics for radiation processing has been studied on the model BPLL readout equipment. The range of linear dose response is in the 10,2,~10,4, Gy. The dependence of light yield on the temperature of solvent and the mass of samples and the storage effect of samples after irradiation are disscused.
