ABSTRACT:
A gas dosimeter comprises a strip substrate coated or impregnated with a color-changing reagent; the strip is disposed lengthwise in a transparent tube, one end of which is openable and is spaced by a diffusion path from one end of the strip. When the dosimeter tube is opened and exposed to the atmosphere containing detectable gas, a color change develops lengthwise of the strip dependent on the dosage exposure to the gas.
