Description

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!

Features

  • Portable, practical.
  • 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.

Virtuoso application provides:

  • information about the status of the detector, dosimetric and spectrometric data which is transferred via Bluetooth from Virtuoso detecting unit to a smartphone or a tablet (Android-based);
  • display of gamma radiation dose rate and amplitude gamma spectrum in graphical view;
  • detection of cesium isotopes in food, soil and wood, evaluation of their specific/volume and surface activities, evaluation of dose rate from cesium;
  • detection of naturally occurring radioactive materials (K, Ra, Th), evaluation of their specific/volume activities;
  • possibility to check the measurement quality of the device using standard metrological samples in Marinelli vessels;
  • both beginners (simplified display of measurement progress in the “Found-Not found” mode) and experts (display of activity spectrum and trends) can operate the device;
  • reports about measurement, their transfer to PC via Bluetooth, email, etc.;
  • automatic adjustment of the detector’s spectrometric parameters at each measurement, device calibration in a separate mode;
  • making and receiving calls, sending and receiving messages, starting and using other applications, etc., without interrupting the process of measurement and loss of data.
