Abstract

A methylene blue-PVA system has been tested as a krad range dosimeter. Mb dye films were fabricated by casting PVA in solution with the methylene blue. In the air the system was irradiated by X-ray and the decolorisation of the dye film was found to remain unchanged for sufficiently long time. The radiation response on optical density at 670 nm in the Mb-PVA system shows a quite good linearity and reproducibility in the krad range.
