A new dose reading system for radiophotoluminescence(RPL) glass dosimeters was constructed by the use of a highly repetitive Q-switched solid state laser in place of a conventional nitrogen gas laser. It was confirmed that the high repetition rate of laser pulses for the excitation was effective for the improvement of the signal-to-noise ratio in the RPL measurement and eventually led to the improvement of the sensitivity of the dose reading system. In addition, several optical improvements were made for the avoidance of the annealing effect in the RPL measurement. The performance tests with normal RPL glass dosimeters indicated that the new dose reading system had high sensitivity and good long-term stability in radiation dose measurement.
