Gamma-Ray Incident Dose Detection Method Using Commercial-off-the-shelf (COTS) Image Sensors

This study conducted ⁶⁰Co gamma-ray irradiation experiments on commercial-off-the-shelf (COTS) image sensors, analyzing the quantitative relationship between dark current amplitude distribution characteristics and incident dose. A dark current distribution model was established, and a novel incident dose prediction method based on statistical feature fitting was proposed. Experimental results demonstrate that the prediction errors remain within 15%.
