The measurement of 129I in ferromanganese crusts and aerosol samples with AMS at CIAE

The determination of long-lived nuclide 129I in terrestrial formations has many important applications. The AMS measurement method of 129I has been set up for many years at China Institute of Atomic Energy (CIAE). For further exploring the potential applications of 129I, samples of Deep Sea Ferromanganese Crusts (DSFC) and aerosol were analyzed by Accelerator Mass Spectrometry (AMS). The results show that 129I is not only a good tool for dating, but also an ideal nuclide for nuclear safety monitoring. The newest experimental progress and the main results are detailed in this presentation.
