The analysis was first done non-destructively by low-level γ-ray spectrometry. Then, April 25 – 29, 23 a radiochemical procedure based on microwave digestion or leaching and followed by extraction chromatography was developed to isolate the actinides, Ra and Sr from the matrices. The U.S. National Academies (NAS) and the Russian Academy of Sciences (RAS), building on a foundation of years of interacademy cooperation, conducted a joint project to identify U.S. and Russian views on what the international nuclear security environment will be in , what challenges may arise from that environment, and what options the U.S. and Russia have in partnering to address those.

Dr. Thorsten Stumpf gave lectures at the KIT Campus South, Department Chemistry and Bio-sciences, in the field of chemistry of f . Gamma-spectrometric analysis and radiochemical determination of 90 Sr content were carried out from the same sample. Then the samples were sequentially treated by water with natural hydrochemical composition, 1M solution of ammonium nitrate, and concentrated acid solutions.
