RADON-4 is a digital handheld personal alpha (α), beta (β), gamma (γ), radon (Rn) and X-ray radiation meter that is designed to monitor and measure equivalent dose rate of radiation.  The device is very sensitive and can detect even small sources of radiation, including Rn in gaseous form that can gather in basements and other closed areas.

RADON-4 radiation detector is lightweight, small and easy to use. It can be carried in user’s pocket or on belt and is a good companion when visiting areas and buildings with possible threat of radiation. Visual and audible alarms alert the user immediately if the radiation dose rate exceeds the programmable threshold level. Each detected event is accompanied by a beep sound; a full alarm is sound for higher radiation levels. An LCD display is programmed to display equivalent dose rate or number of radiation pulses in CPM.

RADON-4 has a precision mode for longer and more accurate measurement.

The device can be set up and controlled by a single button. Due to the long battery life the device can be turned on for extended periods of time for longer monitoring.
