Radioactive tracer $$^{132}$$Cs (TRACs) for Fukushima Nuclear Power Plant accident

Nagai, Yasuki; Makii, Hiroyuki   ; Namiki, Shinji; Iwamoto, Osamu  ; Iwamoto, Nobuyuki  ; Sawahata, Hiroyuki*

We propose to use the radionuclide $$^{132}$$Cs as a tracer. $$gamma$$-ray energy of the most intense line from the decay of $$^{132}$$Cs is 668 keV, which is very near to that of the 662 keV from the decay of $$^{137}$$Cs, while the half-life of $$^{132}$$Cs is 6.5 d. $$^{132}$$Cs can be produced by nuclear reactions such as $$^{133}$$Cs(n,2n)$$^{132}$$Cs, $$^{133}$$Cs(r,n)$$^{132}$$Cs or $$^{132}$$Xe(p,n)$$^{132}$$Cs. The $$^{132}$$Cs tracer would be useful in the quantitative studies of radionuclide $$^{137}$$Cs contaminant in human, and in any experimental studies in the minimization of radionuclide $$^{137}$$Cs contamination in agricultural and stock farming products.
