Pu-236 has been produced by the reaction U-238(p, 3n)Np-236s --> Pu-236 on
an MGC-20 cyclotron at the Abo University. Nanograms of plutonium have been
separated from the irradiated uranium target in two stages, namely, anion
exchange and extraction chromatography with the use of DEHP. Efficient remo
val of uranium, neptunium, and fission products from plutonium has been ach
ieved.
