This is a tiny Russian-made radiation detector, small enough to be attached to your keyring for constant round-the-clock monitoring.


Using a semiconductor type detection array it is sensitive to Gamma Radiation and alerts the user to elevated levels with sequences of beeps or ‘chirps’. The number of beeps corresponds to rad levels , from 0.5uSv/hr (normal, single beeps) to 2000 uSv/hr (very bad! 5 beeps). Powered by a single CR1620 lithium battery; low battery indicated by one long and three short beeps.


Supplied with instructions in English and battery (remove insulator disc before use). In as-new condition and full working order.
