Abstract :
In this paper we report a feasibility study of the gamma ray transmission imaging using a double gap resistive plate chamber. The detector consists of two layers of 2 mm resistive plate chamber (RPC) gaps with two-dimensional read-out strips of 10 mm pitch. Gamma ray transmission images for objects inside a cabinet, using a 10 mCi 137 Cs isotope, were obtained with a pixel resolution of 5 × 5 mm 2 . RPC sensitivities for various gamma ray energies were evaluated by the GEANT-based simulations.
