This document presents radiation resistivity of various polymeric materials with collected data tables that are the candidate materials to be used in the High Intensity Proton Accelerator Facility Project, J-PARC, which is to produce MW-class high power proton beams. The effect of radiation damage and deterioration by loss-beam or secondary particle beam influences the performance and the reliability of various instruments. The radiation damage consists of mechanical property, electrical property and gas-evolution property, and these properties depend entirely upon the kind of radiation, energy and dose intensity. The first part of this document methodically introduces the general feature of polymer and its radiation-induced deterioration mechanisms, and the second part of the document shows the compiled data for irradiation effects of polymeric materials. The sources of the data are the published reports from the worldwide references.

The radiation technologies for environment conservation are useful for purification of pollutants contained in flue gas or wastewater at very low concentration which is difficult to perform by conventional methods: removal using fine filter or charcoals and decomposition using catalysis at high temperature, etc. This paper reviews some examples of radiation application to removal of SO
and NO
from coal-combustion flue gases, decomposition of dioxin in gas emitted through the incinerator, decomposition of gaseous toxic volatile organic compounds in off gas, reuse of agricultural wastes.

The research on electron-beam treatment of VOCs (volatile organic compounds) was presented at 10th international conference of Air Pollution 2001 in Italy. The presentation referred to the decomposition products and active species that oxidize the aromatics and aliphatics. Also, the test facility for EB treatment of PCDD/F from MSWI was presented.

In the field of uranium ore refining and spent fuel reprocessing, a lot of extractants capable of recovering actinides have been innovated, and some of which have been developed in actual industrial scale processes. Extractability against trivalent actinides on each extractants were evaluated in this report. And as for the compounds which showed excellent extractability for Americium, their extraction characteristics for trivalent actinides, such as extraction behavior, mechanism, ligand structure and conformation of complexes, were evaluated, and filed as data-base. Based on these works, some of extractant were newly identified as candidate to apply Americium recovering. The most appropriate compounds for trivalent actinide separation can be generally found in the neutral bidentate organic compound groups: Especially, some derivatives belongs to Diphosphineoxide, Carbamoyl-methylphosphine oxide and Propandiamide were superior to give sufficiently excellent property even in higher nitric acid(1
3M) solutions. Innovative research towards developping new extractants and extraction system seems to be directed to ; (1)investigate new types of extractant sustained by a different kind of complexing mechanism, (2)evaluate synergistic effect of adducts, diluents even including conventional extractants.
