Abstract
A radiochromic plate based on a reversible change between iodide and iodine was prepared using a polyvinyl alcohol–iodide complex, silica nanoparticles, and agarose. X-ray (30 kV, 15 mA) irradiation of the plate changed it to a red color, which gradually disappeared and was completely erased within a day after stopping X-ray irradiation. The minimum detection dose was about 0.5 Gy for X-rays and 10 Gy for 137Cs γ-rays. The G-value for the oxidation of I− was estimated to be about 19.6 in a neutral solution and about 20.64 in an acidic solution.
