A device for chemically quantifying ethylene oxide exposure is disclosed as are methods for its use. The device comprises an ethylene oxide-permeable layer exhibiting unusual non-Fickian EO transport and containing a controlled amount of compound which forms a colored species upon reaction with ethylene oxide. Optionally, the response layer is laminated or otherwise joined with a support layer. The device can be used to quantify in industry accepted units of time and concentration sterilization dosages of ethylene oxide.

A device for colorimetrically quantifying exposure to ethylene oxide which comprises a polymer substrate which exhibits Case II-transport for ethylene oxide through the body of which is dispersed a concentration of a color-forming compound which undergoes a color-change upon reaction with ethylene oxide, said concentration being chosen to provide a variable degree of color-change in said device which, at a uniform temperature, is a previously determined function of the device\s quantity of exposure to ethylene oxide.
