Description

The severe accident of Fukushima Daiichi Nuclear Power Plant made a large area of agricultural land contaminated with radioactive cesium (Cs-134 and 137). Quantitative analysis for radioactivity (discriminating for Cs-134 and Cs-137) taken in vegetables from the land was carried out using NaI (Tl) scintillation spectrometer. Development of gamma camera for their imaging due to Cs 137 was performed. The shape of the peaks in the spectrum, baseline suppression, a solution of lines overlapping, enhancement of high-resolution were studied. Furthermore, the effect of water on cesium absorbing and transferring process from the root to the tissue was studied. (S. Ohno)
