The radioactive material in urine after parenteral radioactive hydroxocobalamin is composed of radioactive cyanocobalamin, radioactive hydroxocobalamin, and a radioactive anionic complex. Studies in vitro suggest that these materials have a similar microbiological activity. Comparison of the amounts of radioactive and microbiologically active material in urine after parenteral radioactive hydro...

This paper presents the accumulation process of radioactive Cs in edible mushrooms. We here first report the direct accumulation pathway of radioactive Cs from contaminated wood logs to the fruit-bodies of shiitake mushrooms through the basal portion of the stipe. In this pathway, radioactive Cs is not transported through the hyphae. This pathway results in a high accumulation of radioactive Cs...

The accident at the Fukushima Daiichi Nuclear Power Plant in 2011 released many radioactive elements into environment, contaminating a large amount of soil. Currently, 14 million m3 contaminated soil is scheduled for interim storage, and final disposal planned by 2045. In future, decommissioning plant will generate great waste. Therefore, reduction volume soil, which accounts ~90% wastes, probl...

We propose a projection-based monolithic model order reduction procedure for class of problems in nonlinear mechanics with internal variables. The work is motivated by applications to thermo-hydro-mechanical (THM) systems radioactive waste disposal. THM equations the behavior temperature, pore water pressure, and solid displacement neighborhood geological repositories, which contain are respons...

Recent research in the field of oil and gas geochemistry has focused on catalytic role minerals geological history. Thermal simulation experiments are considered a valuable means studying formation transformation hydrocarbons. In this paper, we review mechanisms, processes, various arguments for different types thermal from perspective mineral additives. We focus two categories: (1) that provid...
