| Outline of Final Research Achievements |
Large amounts of radioactive materials emitted by the Fukushima Daiichi nuclear power plant (FNPP) accident in March 2011 have led to a heavy environmental pollution.
GE gamma-ray spectrometry detected peaks from Cs-134 and Cs-137 in the organs and fecal samples of cattle. The concentration of radioactive Cs was high in the fecal samples. It was considered that the intestinal bacteria could uptake and eliminate radioactive Cs. Actually, uptake % ranged from 38 to 81 in various intestinal bacteria. Although we tried uptake of radioactive Cs by probiotic bacteria, the uptake % is low. The difference between intestinal bacteria and probiotic bacteria was based on the assay medium. Our result suggested that K inhibit the uptake of radioactive Cs.
