文摘

The facility for delayed neutron counting was built at the China Institute of Atomic Energy in the 1980s. A method of normalized decaying curve of delayed neutron is proposed in this work. Preliminary experiments show that this method is suitable for the determinations of uranium in samples with a wide range of uranium concentrations.
