| Outline of Final Research Achievements |
The accident of the FDNPP on March 2011 had contaminated with radioactive cesium on the wide eastern area of Fukushima prefecture. The followings need to be clarified to predict dynamics within the cattle for the establishment of countermeasure against the contamination: 1. Transfer of radiocesium from feed to the cattle, 2. Transfer of radiocesium within the cattle by the metabolism. In this research, distribution of radiocesium within the body of cattle that was lived for more than 5 months on the grass therein. A compartment model was applied to the radiocesium concentrations of tissue, urine and blood.
Radiocesium concentration in muscle is 30 fold greater than that in blood. Also suggests that 137Cs tends to accumulate into muscle. The results support the conventional cesium metabolism model “radiocesium accumulated in the muscle is slowly discharged from the body by the route of blood, kidney and urine”.
