Abstract
Fricke dosimeter solution in chemical dosimeters consists of Ferrous sulfate, Sodium chloride and Sulfuric acid. Authors made a new experiment on the characteristics of dosimeter solution with Ammonium Thiocyanate and the results obtained were as follows; 1. The chemical oxidation response after irradiation was very rapid(within fifteen minutes). 2. A preventive measure of the spontaneous oxidation as time goes on was possible to use 0.1 mM instead of 1mM Ferrous sulfate solution. 3. 477nm in wavelength of spectrophotometer was most ideal to measure optical density in this solution
