The BioEchem Microwave Radiation Detection Bracelet is able to detect excess microwave radiation emissions from microwave ovens, cell phones, and wifi. For microwave ovens, by placing one of these bracelets near the crack of the door in a microwave oven,  if the embedded red LED light on the bracelet turns on, then it's leaking more than the FDA allowed amount of 5mW/cm².


These bracelet is made from polyester gel with mixed color strips, and are 6 cm in diameter.
