Special purpose radiometric installation РЭУС-II-4
•Special purpose radiometric installation РЭУС-II-4 is used to provide metrological activity measurements of samples (food, environmental media and biomaterials)
•The installation measures activity of volume sources by photons emission with the energy 0,06-3MeV in 2 measuring geometries:
“Marinelli-1l” -1M; “Denta-0,1”-up to 1
•With the duration of measurement ›6 hours,
the error for confidential efficiency of 0.95 is:
•60-15% in the range of 2-100Bq;
•15-12% in the range of 100-5×105Bq
•It can be used for accreditation of similar
installations

Laboratory 31 “Radiation control”Qualitative chemical analysis
Qualitative chemical analysis
It is the branch methodology of the 3rd rate accuracy which is used for chemical analysis of silicate and carbonaceous rocks (magmatic, metamorphic and secondary); ores of non-ferrous, ferrous, noble metals, products of their enrichment and processing; environmental objects (soil, ground, plant cinders, clastic deposits, coals); hard and biological phytogenious and animal-origin materials (plants, vegetables, fruits, mushrooms, fish, meat, fur, hair, nails, bones, blood, serum, urina) to detect Ba, Br, W, Hf, Eu, Re, Hg, Fe, Au, Yb, K, Co, La, Lu, As, Na, Nd, Rb, Sm, Se, Sc, Ag, Sr, Sb, Ta, Tb, Th, U, Cr, Ce, Cs, Zn by the neutron-activation analysis (NAA).
