Abstract

Abstract In the current study, we employ the polyvinyl alcohol doped with nickel sulphate (PVA-Ni+2) as a new film for monitoring the absorbed dose in radiation processing facility. The effect of irradiation doses on the structure of PVA-Ni+2 composite films was analyzed through Fourier transform infrared and X-ray diffraction techniques. The PVA-Ni+2 composite films have a response curve that extends from 5 to 60 kGy and labeling character figured through color change from pale green to intense purple color on exposing to gamma photons. Although the films are dose rate dependent, the films have excellent post stability.
