We are developing a new imaging method to estimate the direction of gamma-ray sources from the response patterns of detectors. In this study, the applicability of the method to simultaneous imaging of multiple sources and multinucleate sources was examined by simulation. As a result, it was shown that simultaneous imaging of ¹³⁷Cs and ⁵⁷Co sources at a distance of 3 m with an angular resolution of about 10 degrees is feasible. The imaging intensity of each source is almost the same, which is expected to be applied to the quantitative evaluation of radioactivity in the future.
