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 hermetically 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.
