Ni2+ ion is proved to precipitate in a solution saturated with H2 by the aid of 60Co γ-ray irradiation. The amount of Ni precipitated increases in proportion to the total dose, where the G(Ni) is accounted for as 0.29. A log–log plot has revealed that precipitation increases linearly with dose rate under less than 1 kGy/h, followed by a subsequent levelling off. In regard to the effect of initial [Ni2+], the increase in [Ni2+] has incurred a reduction of precipitation rate of Ni.
