A laminated material composed of glass cloth/polyimide film/epoxy resin will be used as an insulating material for superconducting coil of ITER. In order to keep safe and stable operation of the superconducting coil system, it is indispensable to evaluate radiation resistance of the material, because the material is exposed to high radiation field of 10MGy at low temperature of 4K. In this work, the gas evolution from the laminated material by ray irradiation at liquid nitrogen temperature (77K) was investigated, and the difference of gas evolution behavior due to difference of components in the epoxy resin was discussed. As a result, it was found that the main gases from the epoxy resin by the irradiation were hydrogen, carbon monoxide and carbon dioxide, and that the amount of the gases from epoxy resin containing cyanate ester was 30-40% less than that from the epoxy resin containing tetraglycidyl-diaminophenylmethane (TGDDM).

We have developed silicon carbide (SiC) products such as SiC fiber with average diameter of 5
m and SiC coating for gas separation membrane from a polymer blend of polycarbosilane (PCS) and polyvinylsilane (PVS). One process for fabrication of SiC product is as follows: forming of polymer, curing of polymer with radiation oxidation, and pyrolysis of cured polymer. In this process, we have found that the PCS-PVS polymer blend can be cured by radiation oxidation with the half dose of that of the PCS. In this work, a behavior of radicals in the PCS-PVS polymer blend was investigated in order to elucidate the mechanism of radiation oxidation of the PCS-PVS polymer blend. It was found that the PVS does not affect on production of the radicals in the polymer blend, and that the radicals are decayed easily by blending PVS in case of the irradiation in air at room temperature.

Removal technology for cadmium ion (Cd
) from the mid-gut gland in the scallop processing was developed by combining the Cd leaching process with malic acid solution and Cdadsorption with graft adsorbent. Experimental equipment was assembled for removal of the Cd from 30 kg of mid-gut gland. The concentration of Cd in the mid-gut gland was reduced from 25 mg/kg to 1mg/kg after 24h treatment. The treated mid-gut gland can be used for fertilizer, animal food, food additives, and supplement.

Biologically originated polymer, polylactic acid, became commercially practical in a limited area owing to its low impact resistance. Elastic sheet of polylactic acid was obtained by dipping the radiation crosslinked polylactic acid into plasticizer heated up to 120
C. Without crosslinking, the polylactic acid cannot soak plasticizer since it was crystallized in the hot plasticizer.

Biodegradable polyester, polyhydroxybutylate (PHB), was irradiated with 10 kGy of electron beam and then was grafted by vinyl acetate (VAc) in emulsion state and solvents of methanol and water. In the case of emulsion state, the degree of grafting reached 23% at grafting temperature of 60C after grafting time of 5h. In this case, grafting percentage of VAc was 1%. The grafting percentages were 0.67 and 0.030% for water and methanol, respectively. It was found that emulsion state can realize the effective grafting of VAc onto PHB.
