Description

VIRTUOSO is a compact-size device for a comprehensive radiological examination of the environment, food, soil, construction materials, mineral raw materials, housing, etc.

Thanks to the use of brand-new technology, you can now control cesium radioisotopes and naturally occurring radioactive materials not only in specialized laboratories but at home without the help of professional radiologists.

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.

Purpose of Use

Detection of 137Cs and 134Cs cesium radioisotopes (hereinafter – radiocesium) in food and objects of the environment
Evaluation of the detected radiocesium content in the quantities of specific, volume, and surface activity
Control of the level of background radiation in the environment, including assessment of radiocesium radiation level as the value of ambient dose equivalent rate purely from radiocesium as the part of natural background
Measurement of specific and volume activities of naturally occurring radioactive materials 40K, 226Ra, 232Th (hereinafter NORM) in the objects of the environment
Track recording with measuring points referenced to geographical coordinates

Branches of Use
