I found a very interesting news on the Japanese newspaper. http://translate.google.co.jp/translate?js=n&prev=_t&hl=ja&ie=UTF-8&layout=2&eotf=1&sl=ja&tl=en&u=http%3A%2F%2Fwww.minpo.jp%2Fview.php%3FpageId%3D4107%26blockId%3D9873865%26newsMode%3Darticle
Dr. Kazue Tazaki supposes radioactive cesium was transmuted to barium by the metabolism of bacteria. It's similar to the following article by Dr.Vysotskii. http://www.iscmns.org/CMNS/JCMNS-Vol4.pdf JOURNAL OF CONDENSED MATTER NUCLEAR SCIENCE VOLUME 4, February 2011 Low-energy Nuclear Reactions and Transmutation of Stable and Radioactive Isotopes in Growing Biological Systems Vladimir I. Vysotskii and Alla A. Kornilova In the article, Figure 9. shows "Accelerated deactivation (accelerated rates of decay) of Cs137 isotope in biological cells in presence of different chemical elements". The most rapidly increasing decay rate is near 310 days. He wrote a possible reaction of radioactive Cs137 isotope utilization is Cs137 + p1 = Ba138 + 5.5 MeV. --Sengaku
