Large-scale irradiation experiments for radiation detection require specialized facilities and strict safety management, making their use in education difficult. This study investigates gamma-ray detection using perovskite materials and commercially available LEDs as low-cost and accessible alternatives. Gamma-ray irradiation was performed using cobalt-60 and strontium-137 sources, and radiation-induced signals were successfully detected with both materials. Perovskite materials showed higher detection frequency due to their larger active area, while LEDs exhibited high sensitivity with lower frequency. These characteristics suggest that both devices can serve as useful educational examples for radiation detection experiments.
