Gasochromic properties for hydrogen gas on tungsten oxide thin films have been investigated for an optical hydrogen gas sensors. The gasochromic properties are considered to relate to oxygen vacancies or defects in the tungsten oxide. In this study, it is tried to make oxygen vacancies or defects in the tungsten oxide thin films by ion beam irradiation, to investigate the relation between the amount of fluency and the gasochromic properties. The coloration for 1 % hydrogen was measured by time resolved optical spectroscopy with 630 nm light. The coloration is enhanced with the increasing the fluence, over 
ions/cm

The charge states were measured for the constituent ions of 1 MeV/atom C
ions passing through a carbon thin foil. The constituent ions of C ions deflected by the deflection plates were detected with a luminance plate position detector monitored by a CCD camera. Since the detected ion signals contain the information of charge states and cluster structure, this measurement method enabled us to investigate the structure-dependent of the average charges in the cluster ions. The data clearly show that the measured average charges of C ions in a linear-chain structure are larger than those in a ring structure. Moreover we found that the edge-position ions in a linear structure have the average charges larger than the middle-position ion. These experimental results are well supported by a recent theory on the cluster average charge.

Ionizing radiation has been used for reducing food losses and securing food safety. The development of versatile detection methods of irradiated foods is needed for appropriate management. In an effort to distinguish between irradiated and non-irradiated meats, a detection method of oxidative DNA base damages using chemiluminescence enzyme-linked immunosorbent assay with anti-8-hydroxy-2'-deoxyguanosine antibody was developed. The procedure of this method is not so complicated, and relatively short time is needed to obtain results without special techniques. For most of all foods containing DNA, this novel method should be applicable to detect the damaged DNA of irradiated foods. Application to beef meat irradiated with 3 kGy or higher was suggested to be detectable successfully.
