Pay Over Time with Bread Pay™


NukAlert Personal & Compact Key Chain Attachable Radiation Monitor & Alarm is More than just a radiation detector, the NukAlert Personal & Compact Key Chain Attachable Radiation Monitor & Alarm   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.

Carried everywhere your keys go, with NukAlert’s 24/7 constant radiation monitoring, you’ll always be promptly alerted to the unseen, but acutely dangerous, levels of radiation if/when present. A benefit of the NukAlert™ radioactive material detection, not to be overlooked, is that it will also confirm when and where those high levels of radiation are not present, too.

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. With the anticipated general public angst accompanying any future developing nuclear emergency it will be very reassuring to know with confidence that, for your locale, your family is out of the worst danger.

    Excellent item because it can always be with you. Manufacturer claims that relative to the beep scale, the true radiation level may be more or less by a factor of two. I tested three of them against a 500 Roentgen cesium-137 source, and they are actually off (reading too high or too low) by a factor of four. But, that is plenty good enough to tell you when it is time to go elsewhere, and when you have arrived at a safer place that has fewer beeps in the beep string and therefore less gamma radiation. Definitely worth $150 unless you think your life is worth less than that. I got one for every member of my family, and will be getting more so they don’t have an excuse to be without. Related product is no longer available to the civilian market, since the government knows what is coming ahead of you and is getting all they can get for themselves.
