Abstract
237U was prepared by 238U(γ,n) reaction on an electron accelerator (MT-25 microtron) at FLNR. The radiation yield of 237U was 1 Bq/(μA h mg 238U). 237U was recovered from the target by collection of recoil nuclei in the solid:solid system. Group I–III element fluorides were used as the 237U acceptor. 237U was separated from the fission products by extraction and ion-exchange procedures. The specific activity of 237U in the sample was 49 500 kBq/mg 238U. The content of radioactive impurities in the preparation was no higher than 10−5. The chemical yield of 237U was 70%.
