RADEX Pocket Geiger Counter II is the new addition to the RADEX family of radiation detectors and monitors. This device can be used not only by professionals working with sources of ionizing radiation, but also by average consumers interested in checking the contamination of places and objects, and knowing the results with high degree of precision.

RADEX Pocket Geiger Counter II is capable of:

increased precision of indications;

expanded range of indications (to 999.0 µSv/h). Range of measured Gamma radiation energy: 1-1.25 MeV. Range of measured X-ray radiation energy: 0.03-3.0 MeV. Range of measured Beta radiation energy: 0.25-3.5 MeV.

time of continuous operation: ~500 hours;

able to register x-ray radiation;


This model uses two SBM20-1 type Geiger-Muller counters, one each for beta- and gamma-rays. The use of two separate sensors allowed us to reduce time of observation to 26 seconds while improving accuracy and precision of results. The range of indications was expanded 100 times, compared to RADEX RD1503. RD1706 can register the value of a doze-rate as high as 999.0 µSv/h. Time of observation automatically adjusts from 26 seconds to as low as 1 second when presence of strong radiation sources is detected. This is necessary to ensure safety of professionals working with or operating ionizing radiation sources.

Most other features from the RADEX Pocket Geiger counter were also retained, i.e. the usual frame with a large LCD screen, three operation buttons, battery charge indicator, display backlighting and personal settings like threshold alarm activation, alarm strength, backlight option.
