The Model 901 Key Chain Radiation Detector for Upper-Range Radiation is an effective and easy to use system for detecting dangerous levels of radiation.

More than just a radiation detector, the NukAlert™ is a patented personal radiation meter, monitor and alarm. Small enough to attach to a key chain, the device operates non-stop, 24/7 and will promptly warn you of the presence of unseen, but acutely dangerous levels of radiation.

Used nationwide by federal, state and local first responders, law enforcement and the Dept. of Defense, the device is the ideal solution for increasing individual security and awareness of radiological threats. It will be very reassuring to know, with confidence, when you and your family are out of the worst danger.
