title: The stability of plutonium sulphate tetrahydrate, an analytical standard: a ten-year evaluation.
abstract: The stability of plutonium sulphate tetrahydrate, Pu(S0(4))(2).4H(2)O, an analytical standard for plutonium, has been studied over periods of up to 10 years, and at relative humidities of 95% and les than 0.1%. The material was found to be stable with time; it was slightly affected by extremes of humidity but the changes were readil reversible.
