  • Distribution of radioactive cesium and stable cesium

    The kidney showed the highest concentration of radioactive cesium among internal organs, whereas the liver was lowest. Radioactive cesium concentration in the blood was about 8% of that in the neck muscle. Characteristics of stable cesium distribution were almost the same as those of radioactive cesium. Correlation coefficient between radioactive cesium and stable cesium in

  • Radioactive and stable cesium isotope distributions

    2018-6-1 · The radiocesium distribution between the aboveground biomass compartments at Yamakiya during 2014–2016 was gradually approaching a quasi-equilibrium distribution with stable cesium. Strong correlations of radioactive and stable cesium isotope concentrations in all compartments of the ecosystem have not been reached yet.

  • Abundance and distribution of radioactive cesium

    2020-2-1 · The abundance and distribution of highly radioactive cesium-rich microparticles (CsMPs) that were released from the Fukushima Daiichi Nuclear Power Plant (FDNPP) during the first stage of the nuclear disaster in March 2011 are described for 20 surface soils collected around the FDNPP.

  • Distribution of Radioactive Cesium ( 137 Cs) during

    The distribution of radioactive cesium (137 Cs) from noodles to broth during noodle cooking was investigated using rice noodles differing in firmness.The firmness of rice noodles was controlled by the gluten concentration, 5%, 10%, and 20%, in rice powder.

Through this airborne moni-toring, in addition to the spatial dose rates and distribution of deposition amounts of

  • Distribution of Radioactive Cesium during Rice Cooking

    The dynamics of radioactive cesium (134 Cs plus 137 Cs) during rice cooking were investigated to examine the effect of rice bran removal ratio on the distribution of radioactive cesium in the cooked rice fraction.The removal ratios of bran used in this study were 0, 30, 50, 70, and 100%. The radioactive cesium in brown rice, pre-cooked rice, cooked rice and washing water were

  • Radioactive and stable cesium isotope distributions

    2018-6-1 · The radioactive cesium distribution in our study in 2014 was closer to that reported for mature Japanese cedar in 2013 by Coppin et al. (2006), with the low fraction in the wood compartments and the largest fraction in the tree trunk. Since 2015, however, clear trends indicate that radiocesium distribution is approaching a quasi-equilibrium
