The Nuclear Residue Detector cum Radiation Alarm (NRD) is designed to alert you of the presence of dangerously high levels of material emitting Gamma rays / X-rays, by producing an audible alarm. The approximate radiation exposure is indicated by the rate at which the NRD emits the alarm inform of a ‘chirp’.
Small enough to attach to a key chain. The device is an ideal solution for increasing individual security by giving an alert of radiological threats. Higher the radiation, more the ‘chirps’ / alarm. The device has a long life of more then 8 years without change of battery.
The device is ‘ON’ 24/7, non-stop and will promptly warn you of the presence of unseen, but acutely dangerous levels of radiation of gamma rays.
The device is made and patented in USA.
