Keywords:β-decay, Shorten the Decay Time, Nuclear Exitation

We have been trying to shorten the decay time of long-lived β-decay nuclei by nuclear excitation for the purpose of reducing the Cs-137 pollution in Fukushima.
Both results of La-138 irradiated by Co-60 and electron linear accelerator seem to be reduced the activity respectively.
