Abstract: A radiation sensor, comprising a housing, a first chamber disposed in the housing and configured to contain a microorganism. A second chamber is disposed in the housing and configured to contain a fermentation material, the second chamber separated from the first chamber by a breakable separator. A breaking member is configured to break the breakable separator when pressed by a user. A flexible membrane is configured to flex when the microorganism ferments and thereby releases a gaseous byproduct. An electronic indicator is configured to relay information indicating the amount of fermentation, when the radiation sensor has been exposed to radiation less fermentation takes place resulting in a smaller volume of released gaseous byproduct.
