The RT-22 model is based on the RT-21 series, the most sensitive from the range of manufactured hand-held radiation detectors. Compared to its predecessor, it comes with an internal memory for storing measurement data, and Bluetooth connectivity allowing the use of an external GPS module. Its robust design makes it suitable for hostile climatic conditions. Our bestseller at the time of the uranium panic. Popular with scrap yard owners.



Large NaI/Tl detector. Search profiles recordable in memory. Data transfer via USB or Bluetooth. Well balanced and easy to carry. Robust boot for mechanical protection.


Sensitive localisation of sources of radiation. Widely used in metal recycling and exploration.


The only detector with a NaI/Tl scintillation crystal with a capacity of 104 cm3 weighing less than 3 kg. Its housing is made of aluminum alloy coated with a polyurethane layer. This protects the device from wear and tear and allows for easy decontamination. The presence of radioactive substances is indicated on a graphic display, and by a piezoacoustic transducer generating alarm signals. Dust and water resistant. Easy one-button operation. Low power consumption and long battery life. Rechargeable AA batteries can be used. The charger is integrated in the device. An AC adaptor is supplied for charging/powering from the mains, and the unit may be powered from a 12V car socket. 

Compared to the RT-21 series model, it comes with data memory for data logging of measured profiles. An external GPS module connected via Bluetooth allows the user to add location information to the stored data. The memory capacity allows storage of data for at least 12 hours.

The RT-22 series is also available with a telescopic arm. At a customer’s request, an RT-22B model is available fitted with a BGO detector instead of a NaI-Tl detector.
