Abstract
A high contrast dosimeter is constructed where a plastic support is at least partially coated with a layer having a colored radical trapping compound. The plastic is a polymer that can contain a radiation sensitive plasticizer. The plastic forms radicals upon irradiation with high-energy (low wavelength) radiation. Upon diffusion of the radicals to the layer of radical trapping compound, reaction forms a compound with a different color than the radical trapping compound. In an embodiment of the invention, the plastic support is celluloid and the radical trapping compound is an azulenyl nitrone (AZN).
