| Abstract: | A radiochromic film dyed with dimethyl yellow (DMY) is blended in matric polyvinyl chloride (PVC). Its color is changed from yellow to red within dose range 15~25kGy irradiated by Cobalt-60 gamma ray. The color of the film is distinguished easily by eyes before and after irradiation and is insensitive to environmental conditions such as light, humidity. It is suitable to be used as "go- nogo" indicator for radiation sterilization of medical devices. |
