In recent years, the demand for low-cost radiation detectors has increased from the perspective of everyday radiation protection. In response to this need, we focused on the conductive polymer polyaniline (PANI), which offers low cost and excellent processability, and fabricated radiation detector materials with titanium dioxide added to enhance sensitivity. The synthesis process and sensor fabrication method of the PANI-based detector are described.We studied the effects of titanium dioxide addition and its compositional ratio on radiation sensitivity.
