Project summary

The goal of the Project is to renovate the neutron-activation analysis laboratory at the Institute of Physics and to provide the services related to elemental analysis of water, soil, air, foodstuffs, medical products, construction materials by neutron-activation analysis. In addition, we will identify and analyze by this scientific technique various dual-use goods, including nuclear and radioactive materials among others.
Identification and determination of substance content are made by instrumental neutron-activation analysis based on activation of nuclei and on gamma-spectrometric measurements of induced radioactivity. Irradiation of samples is carried out by means of the thermal neutron flux in the sub-critical assembly “Breeder-1” (the peripheral equipment will be modernized within the framework of this Project). Analytical measurements will be made using an HPGe semiconductor detector available at the Institute and using other radiation detection instruments that will be purchased during the Project.
The analysis for determination of the content of radioactive elements in water, soil, air, foodstuffs, medical products, construction materials, etc. is also of a great interest in Georgia.
Besides, for Georgia, the uniqueness of the laboratory being setting up is its possibility to test the sample, first, for the presence od radioactive elements in it, and then, for detecting and quantifying heavy metals after irradiating samples with neutrons in subcritical assembly. The preparation of test samples is relatively straight-forward and not labor-consuming. These properties of neutron-activation analysis simplify laboratory analyses, enhance through-put, and reduce analytical costs compared to more expensive techniques such as inductively-coupled plasma mass spectrometry and other chemical analytical tests.
