RADTriage FIT Personal Radiation Detector for Wallet or Pocket,Nuclear Radiation Detector,Electromagnetic Field Radiation Detector,Anti Radiation Dosimeter, Ready-to-Go Portable Radiation Detector

The RADTriage FIT is a credit card sized radiation detector that can be carried daily on a neck lanyard, in your wallet, or (like me, since I do not work in an industry with risk of radiation exposure) on my refrigerator out of direct light. Expiration Dates: If there is no radiation exposure, the sensor is active for up to 1 year at room temperature, or up to 5 years if kept frozen between uses. Once radiation is detected, or if color shows due to misuse, the card needs to be replaced. Damage/Misuse: The card can become damaged and unusable if exposed to airport security or medical X-rays more than 5 times, or if exposed to more than one laundry cycle, or if exposed to boiling water, or if the colors on the card become dark or red. The card's life may be shortened if exposed to temperatures above 72 degrees F for a prolonged period of time, or if exposed to prolonged periods of sun/UV light. Features: The face of the card has a dosimeter reference bar. There is a center rectangle that remains colorless unless exposed to radiation; low radiation turns the strip light green, while greater levels (above 10mSv) are indicated by the color shades on the card above and below the rectangular strip. The card measures gamma/ X-rays (energy higher than 30 KeV), high energy electrons/beta particles (above 0.5 MeV), and neutrons. Radiation Exposure: If radiation is detected, the dosimeter reference bar should be read under a fluorescent light for accuracy. Emergency Phone #s: Agencies listed on the back of the card should be notified of any radiation exposure. The Card's Exposure: The sensor on the card exposes the user to the equivalent of an airport security machine, or a diagnostic dental or chest X-ray. Time to Replace: After one year of correct use at room temperature, the dosimeter will develop color equivalent to 10 mSv and should be replaced. Everyone should have one of these cards in today's political climate. I bought this for our survival/emergency kit, but realized that it also belongs in the house where we can see it daily. The info above was compiled from the literature that came with the card. Hope you find it useful!

Muy bueno

Great product, haven't been able to test it so far. I was expected 20 badges because of the "RADTriage 20 Radiation Detector" but understand the confusion. I needed something a little different and would not have ordered this had I known. That said, I can be careful and still use this product. The only reason I took off a star was because the '20' is still in the title without being part of a serial number or some such.

HOPE I NEVER NEED TO USE IT, BUT GOOD TO HAVE ON HAND

Good item, as advertised, HOWEVER SELLER PACKED two (2) as ordered LOOSE (credit card size) IN Large amazon box with other items! When box damaged in shipping one card of two lost in transit. Reordered via amazon. Must be packed in 8x11 envelope with padding to ensure does not slip out, get lost forcing customers to order replacement

This photo was taken the day the unit arrived. You can see the FIT indicator has already experienced significant wear. The radiation sensor is still good, but this product has been likely exposed to excessive heat in the warehouse. For reference, you can see the photo of the company’s example of what it should look like on arrival.

This is a simple device for radiation works or folks who want to complete their preparations. Inexpensive and easy to use.

Fast shipping and the article arrived unexposed and fit our needs perfectly. This is a *cumulative* detector, and will tell you precisely when you have been exposed to the radiation limits in a broad spectrum. It is *not* a radiation detector like a Geiger counter, and should not be expected to perform such duties. Use the right tool for the job and use it according to the manufacturer's instructions.
