VIRTUOSO is a compact-size device for comprehensive radiological examination of food, soil, construction materials, etc. It can be used for official measurements for environmental studies, radiological control of agricultural products, in construction, mining, logging and woodworking industries, as well as for educational programs.
The device is designed to detect cesium radioisotopes and naturally occurring radioactive materials (potassium, radium, thorium), as well as to assess their specific, volume and surface activity.
Thanks to the use of the brand new technology, you can now control cesium radioisotopes and naturally occurring radioactive materials not only in specialized laboratories, but at home without help of professional radiologists!
VIRTUOSO works with the Android-based smartphones and tablets via Bluetooth. The device is portable and practical, it does not require special users training and operates in the interactive mode.
Creating a new concept of radiation control, we have simplified the process of measurement with no loss of measurement quality, but on the contrary, we have improved and expanded measurement capabilities of the device. In contrast to the time-consuming and cumbersome traditional methods of monitoring radiation contamination, VIRTUOSO performs measurement by simply putting it to the object, or even by holding the instrument in your hands in a certain place that you want to check for contamination. Thus, the item and its packaging remain undamaged.
With VIRTUOSO you can easily check radiation purity of:
– construction materials
– mineral raw materials
and such food as:
– baby food
– water, milk
– meat, fish, eggs
– fresh vegetables, fruit
– grain, cereals
– dried foods
– dried herbs (tea).
Requires no special training of the user, operates in the interactive mode.
Does not require sampling – measurement is done by putting the device to the tested object (material, product, soil, etc.), or by holding it over the studied surfaces.
Requires no special preparation of the food sample (the product remains inside its packaging).
Requires no special protection.

Gamma dosimeter with GPS MKS-UM is a full-range radiation survey device in the field environment. Designed on the basis of MKS-U, which gained an excellent reputation under severe desert conditions during peacekeeping mission in the Middle East.
In addition to gamma and beta radiation the dosimeter can measure alpha radiation. There is an added possibility to archive measurement results with reference to the location coordinates with the integrated dual-system GPS / GLONASS receiver. The device uses lithium-ion memory-effect-free battery. The display indicates the statistical error of measurements. Availability of the analog indicator of radiation intensity facilitates localization of radiation sources. High protection rating IP67 and a rubber protective case allow using the device in harsh climatic conditions. It became even more comfortable to operate the device due to the reduced weight and dimension parameters.
