In this study, the effect of gamma radiation on the pn junction structure in Si semiconductor detectors was investigated using a safe and low-cost Cobalt-60 radiation source. Detectors with different junction surface geometries were fabricated by mask fabrication and anisotropic etching, and the effect of the different structures on the response was evaluated. A charge amplification circuit was used in the experiments to observe the signals. The results show that it is possible to safely and inexpensively observe structural radiation effects on semiconductor devices.
