Rf reaction has been studied by anion-exchange chromatography on an atom-at-a-time scale. The anion-exchangechromatographic behavior of Rf was investigated in 1.9-13.9 M hydrofluoric acid together with those of the group-4 elements Zr and Hf produced in the O-induced reactions on Ge and Gd targets, respectively. It was found that the adsorption behavior of Rf on anion-exchange resin is quite different from those of Zr and Hf, suggesting the influence of relativistic effect on the fluoride complexation of Rf.

We have investigated the sorption behavior of element 104 rutherfordium (Rf) on an anion exchange resin from HCl and HNO solutions. In the HCl experiments, the distribution coefficients of Rf increase with an increase of HCl concentration from 7.0 M to 11.5 M, indicating that anionic species such as [Rf(OH)Cl
]
or [RfCl
] are formed. This sorption behavior of Rf is typical of the group-4 elements Zr and Hf, and is quite different from that of the pseudo-homologue Th. It is also noted that the distribution coefficients decrease in the order Rf, Zr, Hf at 9.0 M HCl, which is consistent with the expected order of ionic radii. On the other hand, Rf appears to behave like Zr and Hf in 8 M HNO not like Pu and Th.

Cosmic ray muons can pass through large structures such as industrial plants and buildings including foundation. Engineering Advancement Association of Japan (ENAA) and Kawasaki Geological Engineering (KGE) have developed an exploration system using cosmic ray muons for detecting underground cavities which have a potential to bring about disasters. Japan Atomic Energy Agency (JAEA) has started an applicability test of this technology to the Fukushima Dai-ichi Nuclear Power Plants together with ENAA and KGE in October, 2012. In the test, core internal structures of the High Temperature Engineering Test Reactor (HTTR) will be visualized to obtain practical data on resolution and measuring time necessary for improving the system.
