| Outline of Final Research Achievements |
Magnetized Prussian blue (PB) was given to the goats feeding the grass mildly contaminated with radioactive cesium (Cs) 137 to investigate whether it would prevent absorption of Cs137 and it could be recovered from the feaces using a magnet hence recovery of Cs137.Almost all the Cs137 was excreted in faeces from the goats resciving the magnetized PB without any noticeable adverse effects. Using a strong magnet, 70% of magnetized PB given to the animal was recovered from their faeces and the estimated recovery of ingested Cs137 was around 75%. The results suggest that using magnetized PB might be useful for comprehensive decontamination in the animal production environment.
