METHOD FOR PRODUCING Ni RADIONUCLIDE PREPARATION OF HIGHER THAN 10 Cu/g ACTIVITY Russian patent published in 2006 - IPC G21C1/02 

FIELD: atomic engineering.

SUBSTANCE: proposed method for producing ⁶³Ni radionuclide preparation having specific activity not over 10 Cu/g includes neutron irradiation of source material in nuclear reactor, production of preparation solution from irradiated material and acid, and extraction of target radionuclide preparation from solution obtained. Source material is metal copper of natural isotope composition with mass fraction of nickel dope not to exceed 5 · 10^-3%. Irradiation is conducted in nuclear reactor at fast (E ≥ 0.1` MeV) neutron flow density of not lower than 8 · 10¹⁴ cm^-2s^-1 and flow density ratio of thermal (E ≤ 0.5 eV) and fast neutrons not over 0.01. ⁶³Ni preparation is extracted by settling down copper from solution made of irradiated material and nitric acid, its concentration being minimum 0.01 mole/l.

EFFECT: facilitated procedure, enhanced safety.
