More than just a detector, the NukAlert™ is a patented personal radiation meter 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 acute & dangerous levels of radiation.
please note : The producer gives a ten year warranty for this item. That creates hope…
I believe this item will become very popular even if quite expensive.
