The exposure of workers in general medicine is mainly X-ray exposure due to scattered rays from the subject. Therefore, the measurement of such scattered radiation is necessary for confirmation of exposure situation and radiation protection. Recently, the new hybrid survey meter RaySafe 452 was released by Unfors RaySafe. However, there are no detailed reports regarding the performance, which includes reproducibility and angular dependence, of RaySafe 452 survey meter. The purpose of this study was to evaluate the performance of RaySafe 452 survey meter. Experiments were conducted to compare the performance of RaySafe 452 survey meter with that of an ionization chamber survey meter. The results showed that the basic performance of the RaySafe 452 survey meter was good compared with the calibrated ionization chamber survey meter.
