Low dose gamma film dosimeter based on chitosan and starch bio-polymer with methyl orange dyes has been synthesized and characterized. The aim of this research was to synthesis radiochromic film dosimeter used biopolymer material such as chitosan and starch with methyl orange dyes as the color indicator and also to investigate the effect of gamma irradiation on film dosimeter response. The film dosimeter was prepared by mixing chitosan and starch at gelatinization temperature then added with methyl orange dyes. Biopolymer solution then casting on the flat glass to produce a thin film with uniform thickness, after that film dosimeter was irradiated at 1, 3, 5, and 9 kGy. To analyze the quantitative response of irradiation, the film dosimeter was characterized by UV-Visible. The result shows that the film dosimeter has changed its color as a response to the irradiation. The higher the dose of gamma irradiation, the higher the net absorbance of it. This research showed that bio-polymer based chitosan and starch is material that has the potential for low dose gamma dosimeter.
