NukAlertTM Nuclear Radiation Detector & Monitor Keychain | Portable Radiation Alarm for Emergency Preparedness, Personal Safety, and Survival | Compact and Easy-to-Carry Radiation Detection Device

Carried everywhere your keys go, NukAlert's 24/7 constant radiation monitoring, alerts you if you are being exposed to dangerous levels of radiation. the NukAlert is a compact key chain attachable radiation Monitor & alarm. Monitoring is always on, using a built in long-life (ten+ year) battery. The devices range encompasses higher emergency radiation levels. There are 10 easily recognizable 'chirping' alarms. The NukAlert has a Patent-Pending 'State of the Art' Detector Technology that has been verified by independent National Radiological Laboratory. Each NukAlert is individually tested for radiation detection accuracy. Package includes an instruction manual with personal nuclear survival strategies. It Meets the FCC and European Community requirements for Electromagnetic Compatibility, emissions and susceptibility. it has also, passed EMP immunity tests and meets the MIL-STD-461D, RS105 standard. its has a 2 year warranty plus a 10 year prorated warranty. NukAlert is made in U.S.A.
