The RADTriage FIT is a credit card sized radiation detector that can be worn on a daily basis on a necklace, in a wallet, or (like I have, since I don't work in an industry). with radiation risk) on my fridge away from direct light. Shelf Life: Without exposure to radiation, the sensor is active for up to 1 year at room temperature or up to 5 years when stored frozen between uses. Upon detection of radiation or discoloration from misuse, the card must be replaced. after more than one wash, or when in contact with boiling water, or when the colors on the card become dark or red. Card life may be reduced if prolonged exposure to temperatures above 72 degrees Fahrenheit or prolonged exposure to sunlight/ultraviolet light. Features: There is a dosimeter scale on the front of the card. There is a central rectangle that remains colorless unless exposed to radiation; Low radiation colors the bar light green, while higher levels (above 10 mSv) are indicated by tints on the map above and below the rectangular bar. The card measures gamma/X-rays (energy above 30 keV), high energy electrons/beta particles (above 0.5 MeV) and neutrons. for accuracy. Emergency numbers: Any exposure to radiation must be reported to the institutions listed on the back of the card. chest x-ray. Replacement time: After one year of proper use at room temperature, the dosimeter will display a color equivalent to 10mSv and should be replaced. Everyone should have one of these cards in today's political climate. I bought it for our survival/emergency kit but found that it also needs to be around the house where we can see it every day. The above information has been compiled from the literature accompanying the map. I hope you find it useful!
