5 INTRODUCTION General methods for reduction (?) of radioactivity 1 Only wash by water 2 Adsorption by zeolites Size of ion (pm) ; contaminated matter? Efficiency of absoption? Cs + Cs 1.65 > K 1.33 > Na 0.98 cesium potassium sodium Oxidation-reduction potential (volts) Na; > Cs; K; As the results, Cs must compete with Na and K 3 Reaction with bacteria & plants Practical use? zeolite S-ist

6 INTRODUCTION what is elimination of radioactivity? ---- genuine method / be true to Nature --- Shield : coolant water just like in the reactor how to shield ray and electron beam change Cs to non-radioactive matter Various kinds of elements have been formed as stable ones since the earth was born.

12 What is the Infoton? Dissociated hydrogen bonds generate the Infoton(s) Registered to Japanese Patent Office, 2008 Infoton H + --e - Similar to EZ water? Symbol mark; <H 2 O = h > bra & ket vector a plasma-like state ( looks like in a metal surface=plasmon) Emit radiation of Far Infrared to THz (10 13 ~ Hz) Long wave length Extended particle like an elementary particle, and described in wave function

14 INTRODUCTION low frequency Macro scopic aspects for shielding high frequency longer wavelength shorter wavelength such as Infoton (ex. Far Infrared and/or THz) (radiation ) -ray ( photon ) is absorbed by Infoton <H + --e - > (left hand side) Shielding=resonance =like resonance circuit in the devices ( Transition of energy is accompanied with an absorption of one quantum )

The levels of Ba, La, and Ce detected after the treatment were markedly different from those usually present in soil. Soil + water filtered, then solutions are analyzed.

27 Summary We found new idea and experimental results for elimination of radioactivity. Theoretical approaches was proposed; 1) To utilize quantum effect of Infoton from treated water. 2) To apply Group theory for reaction between Cs nuclei and Infoton. Confirmed by experimental way 1) Reduction of radioactivity of soils from the nuclear power plant. 2) Stable elements; Ba, La and Ce were confirmed in analysis
