Application

PGNAA Spectrometer is intended for:

Analysis of the radionuclide composition of samples containing trace amounts of radionuclides;

Search for decay products of radionuclides of anthropogenic or natural origin;

High registration efficiencies and low detection limits are achieved with;

Reduction of natural background levels through the use of materials purified from radionuclides;

Increase in peak contrast due to active suppression of Compton scattering quanta.

 PGNAA Spectrometer is applicable in:

Mining and Mineral Exploration: For accurate and rapid elemental analysis of ores and minerals.

Environmental Monitoring: Detecting and quantifying pollutants in soil and water.

Agriculture: Analyzing soil composition to optimize fertilizer use and crop yields.

Petrochemical Industry: Monitoring elemental composition in crude oil and its derivatives.

Geological Research: Studying rock and sediment samples for scientific research.
