Abstract
A low cost, rapid, flexible radiation detector uses inorganic metal halide precursors and dyes that respond to self-quenching hybrid scintillation. Remote, high-contrast, laser sensing can be used to determine when exposure of the detector to radiation occurs (even temporally).
Claims19
A colorimetric radiation detector, comprising:
- a metal halide that decomposes to form a metal and a free radical on exposure to x-ray or ultraviolet radiation;
- and
- a dye whose fluorescence is quenched by a product of the metal halide decomposition.
A method for detecting radiation, comprising:
- providing a colorimetric radiation detector, the detector comprising:
- a metal halide that decomposes to form a metal and a free radical on exposure to ultraviolet or x-ray radiation;
- and
- a dye whose fluorescence is quenched by a product of the metal halide decomposition;
- exposing the colorimetric radiation detector to radiation;
- and
- detecting a change in color of the colorimetric radiation detector.
