SIMS测定国际比对铀微粒中铀同位素丰度

Determination of Uranium Isotope Ratio in Uranium Particles for Intercomparison by SIMS

Abstract: Measurement of isotope ratio of uranium in small amounts were required by nuclear safeguards for the control of environmental contamination and the detection of nuclear proliferation. The isotope ratio of uranium particles were determined by SIMS. The result was agreed with the reference values.
