Spectrometer-dosimeter of gamma-radiation "Rhythm-S"

Purpose:

  • registration of gamma-ray spectra and identification of radionuclides;
  • measuring radionuclide activity in building materials, mineral raw materials, waste products, food stuff and other materials in the Marinelli geometry (without transferring to a laboratory);
  • quick measuring of radionuclide activity in the "2π" geometry (without sampling); • remote measuring.

As a dosimeter, the device is designed for:

  • detection of gamma-ray sources and radiation-contaminated materials;
  • monitoring of transport vehicles crossing national borders;
  • monitoring of radioactive contamination in scrap metal;
  • measuring gamma-exposure rate in the field and in production environment.

Dosimeter "Rhythm-1M" DBG-02 has passed the Government Acceptance Test.

Portable gamma-ray spectrometer / dosimeter "RHYTHM-S" is meteorologically certified.

From 2011 on, the spectrometer "Rhythm-S" will be equipped with a Bluetooth module capable of transmitting data over a distance of up to 100m, i.e. the computer is connected with the point of measuring wirelessly, which allows to be located at a greater distance from dangerous sources of radiation thus reducing the dose received.
