Application of the oxidation of iodide by organic halogen peroxide for a new 3D gel dosimeter

The oxidation of iodide by trichloromethyl peroxide in a 2-propanol/water solution leading to the I 3 − production was applied to a gel dosimeter along with the addition of 5% hydroxy-propyl-methyl-cellulose (HPMC). The dose response was constant at the dose rate of 300 and 100 Gy/h and stable for more than 7 days. For the ion irradiation, the yield of I 3 − at the front of the Bragg peak region was 92–93% relative to that at the entrance.
