Radioanalytical determination of Fe-55 and Ni-63 in the environmental samples
The radioanalytical procedures for the determination of neutron activation isotopes (Fe-55 and Ni-63) in environmental samples (water, sediment, sail and biological material) are described. The procedures are based on the coprecipitation of Fe-55 with iron hydroxide in natural and reactor water, ashing and mineralization of sediments, soil and biota samples, and the sequential separation and purif
