Production Radio-Chromic Films Dosimeter for Low and High Irradiation Dose Application
摘要
The aim of this study is to provide a dosimeter film for industrial and medical applications using different types of dyes with polyvinyl alcohol as support (using a concentration of 10 µm and 30 µm thicknesses of (10, 15, 20 ml), and polyvinyl alcohol (PVA) films were exposure to gamma rays. The films were exposed to different dosage ranges (from 5–60 kGy). Ultraviolet–visible (UV/VIS) spectrophotometer was used to measure the color change of film dosimeter before and after exposure to gamma rays (at 250 to 800 nm), Also the film stability was studied at different time periods 1, 7 and 14 days for all films. These films need further studies with different parameters.
