We have developed a radiation detector that consists of a conducting polymer derived from an organic semiconductor material.In this study, an attempt was made to fabricate sensors with improved β-particle sensitivity by adopting several approaches, including doping inorganic chemicals and using polyaniline with fine-tuned oxidation states. As a result, the target detection efficiency of 20% was achieved in the environment of a university laboratory, which is necessary to commercialize the organic radiation sensor.In this presentation, we report on the fabrication, results and prospects of a new type of sensor that achieves the detection efficiency of 20% for β-particles.
