Abstract: Decontamination of radio-strontium. The proposed colloidally-stable nano sorbent represents reaction product combined with an equivalent amount of calcium cations, or a mixture of barium and sulfate anions in a medium stable emulsion of copolymers of acrylic acid with a particle size of not more than 500 nm. The new nanosorbent is a mobile-selective sorbent, for decontamination of radionuclides strontium, capable, due to its small size of the particles, of penetrating into the pore space of soil, providing efficient extraction of radionuclides.
