Near 50 years history of the development of radioisotope neutron sources in China is briefly reviewed. The structure design, preparing technology and production status of routine neutron sources including 210PoBe sources, 210Po mock fission sources, 241AmBe sources, 238PuBe sources, 252Cf spontaneous fission sources and other specialshape neutron sources are summarized. In addition, the prospects of development on radioisotope neutron source in China are predicted from the needs of nuclear power construction, oil welllogging, neutron moisture gauge and neutron brachytherapy.
