What Products and Services do Harwell Dosimeters make?
HARWELL Dosimeters produces high-quality dosimeters mainly for use in the sterilisation of medical devices. Three types, Red 4034, Amber 3042, and Gammachrome YR are made from radiation-sensitive poly-methylmethacrylate (pmma) in the form of optically transparent pieces individually sealed in laminate sachets. They darken when irradiated, and the radiation-induced darkening, accurately measurable by means of a spectrophotometer, is a function of the radiation dose absorbed. We maintain a page providing technical specifications for each product.
