This paper reviews the present status on the environmental conservation/purification technologies based on ionizing radiation such as treatment of NOx and SOx in coal-combustion incineration flue gas at power plants, decomposition of dioxins contaied in manuciple solid waste incineration flue gas, treatment of volatile organic compounds, and wastewater treatment.

Useful materials for the environmental preservation were synthesized by the radiation-induced graft polymerization and the crosslinking reaction. In the graft polymerization, the fabric adsorbent for metal ions can be synthesized by using the nonwoven as a trunk polymer. Adsorption rate of the resulting adsorbent are 100 times higher than the resin adsorbent and handling is more convenient. This advanced adsorbent led the cadmium removal from the scallop processing waste, the purification of the incinerator washing water, the collection of the uranium in seawater, and the collection of scandium from the hot-spring water. Moreover, the biodegradable material obtained by the radiation crosslinking is used as the bedsore prevention mat and absorbent for excess water from livestock excrements. The thermal property of polylactic acid can be improved by the radiation crosslinking, and the biodegradable heat-shrinkable tube was developed.
