Gamma Ray Spectrometer | RUG 91-2 Gamma-ray Spectrometer

GAMMA-RAY SPECTROMETER

New Approach to Radionuclides Detection in Food and Water.
Over 5000 systems are installed worldwide!

Measurements of partial specific activities of Cs-134, Cs-137, K-40, I-131 radionuclides Optionally Ra-226, Th-232

The RUG 91-2 Gamma-ray Spectrometer (Radiometer) is intended for measuring the specific activity of gamma-emitting radionuclides: Cs137, Cs134, K40, I131 isotopes in foodstuff and liquids (milk, drinking and sea water). Optional possibility for measuring Ra226, Th232 in products of animal or plant origin, soil samples, etc.
Additional libraries are Ba-133, Cd-109, Co-57, Co-60, Mn-54, Na-22, Sn-113, Y-88, Zn-65, Ce-139

Quick	* Reduced volume of sample	Easy-to- use	* Easy set-up for non-experienced users

KEY FEATURES:

        • Sample volume 0.5 l
        • Compact design
        • Small dimension & weight
        • Simultaneous spectra acquisition and processing

OPERATION:

RUG 91-2 Gamma-ray Spectrometer (Radiometer) registers and analyzes the amplitude of photon distribution of pulses generated in the scintillation detector when the gamma-ray quanta of the sample get into it. Then the amplitude distribution of pulses is analyzed and the radionuclide activity calculated. In order to enhance the registration of photon impulses, the sample for Gamma-ray Spectrometer (Radiometer) is placed into the 0.5 liter Marinelli vessel installed in the lead shield which protect from the influence of the external background radiation.

Two modes: Standalone and PC-controlled (through USB).

APPLICATIONS:

        • Food control laboratories
        • Vet clinics
        • Agricultural laboratories
        • Pharmaceutical, processing industry laboratories
        • Industry-specific schools
