We have investigated the effects on electrical and optical properties of Al-doped ZnO (AZO) semiconductor films induced by high-energy heavy ion. The AZO films with c-axis on SiO$$_{2}$$ glass substrate were prepared by a RF-sputter-deposition method at 400 $$^{circ}$$C. Rutherford backscattering spectroscopy shows that the Al/Zn composition and the film thickness are 4 % and 0.3 $$mu$$m. No appreciable change was observed in optical transparency. We find that the conductivity monotonically increases from 1.5$$times$$10$$^{2}$$ to 8$$times$$10$$^{2}$$ S/cm with increasing the fluence up to 4$$times$$10$$^{13}$$/cm$$^{2}$$, as already been observed for 100 keV Ne irradiation. The fluence of 100 keV Ne at which the conductivity takes its maximum is 3$$times$$10$$^{16}$$/cm$$^{2}$$ (7 dpa). The dpa of 100 MeV Xe at 4$$times$$10$$^{13}$$/cm$$^{2}$$ is estimated as 0.008. Hence, the conductivity increase by 100 MeV Xe ion is ascribed to the electronic excitation effects.

It is easy to assume from the past data that microbial transport do not find at 100%-sodium bentonite. Microbial transport do not find at 100%-calcium bentonite too. There are no effects to distribution ration (Kd) of Neptunium (Np) and Plutonium (Pu) with bentonite by sterilizing on low Eh condition (Eh= -500mv). Kd values of Np and Pu show behavior, which are increasing on the hard acidic and alkali conditions. Especially, Kd values of Pu shows one of Kd value is about 100 ml/g on pH=3$$sim$$6, but the other of Kd value is about 400,000 ml/g on pH=13. Precipitating plutonium hydrates occurred the large Kd value on alkali condition.
