Abstract

²³⁶U is a longlived radionuclide with half life of 2.342(3)×107 a. The ratio of ²³⁶U/²³⁸U is about 10-14 in the natural Uranium. The origin and production of 236U in globe are introduced and estimated in this paper，respectively. The major applicationsion of ²³⁶U as a 100 million year neutron flux integrator，as a “fingerprint” for monitoring nuclear environment and nuclear activity，and as a tracer in geological studies are briefly summarized. The accelerator mass spectrometry(AMS) measurement of ²³⁶U in the world and the research on HI13 tandem accelerator at China Institute of Atomic Energy(CIAE) is also mentioned in this paper.
