To understand behavior of iodine in shallow and deep underground is essential because radioactive wastes, which contain high levels of radioiodine, are planned to be stored in underground nuclear-waste repository. We determined iodine distribution, speciation, and isotope ratio (
I/
I), to investigate long-term migration of iodine in diatomaceous and siliceous shales, using core and groundwater samples collected at JAEA Horonobe underground research center. Iodine exists as I- in groundwater, while that in shales is a mixture of organic and inorganic I.

Radioactive Cs was present on the grass and rice stubble on the soils, but not in the soils beneath the grass and rice stubble, indicating that the radioactive Cs was deposited on the grass and the rice plant. In addition the ratio of the radioactive Cs penetrated into soil layer by weathering was very small for two months after the accident. These results indicate that trees and plant would be the reservoir of the fallout Cs and function for retardation of the fallout Cs migration with rain water.

Formation process of samarium phosphate mineralization on the cell surface of microorganisms has been studied. The rate of nano-particles formation on the cells of yeast was lower than that of soil bacteria, suggesting that thicker cell wall of yeast than soil bacteria gave lower release rate of phosphate ions from inside of cells.
