BREAKWATER FOR ADSORBING RADIOACTIVE SUBSTANCE
PROBLEM TO BE SOLVED: To provide a breakwater structure of a low cost which maintains breakwater resistance when tidal waves and the like occur and also adsorbs strontium 90 and the like in radiation-contaminated water.SOLUTION: There is provided a breakwater structure in which a breakwater has fracture resistance against tidal waves and the like occurring on a seawater surface 4 and which adsorbs strontium (Sr) 90 in radiation-contaminated water. The breakwater is formed by partially laminating large stones 2 and pebbles 3 such as "common hornblende" containing potassium and aqueous calcium having larger ionization tendency than Sr between a caisson 5 above a base riprap and upper concrete of the breakwater, so as to slightly penetrate seawater toward the sea at low tide and introduce seawater from another end into the breakwater at high tide. In the breakwater structure, the large number of pebbles 3 are wrapped with a stainless net (mesh) and the like, adsorbs strontium 90 and the like in the radiation-contaminated water and can be replaceable. Further, sunlight guides 8 breed algae which absorb radioactive substances, and an underwater beta ray is continuously monitored by using a radiation detector 9.
【課題】津波等が発生したときの防波堤抵抗力を維持すると共に、放射性汚染水中のストロンチウム９０等を吸着する低コストの防波堤構造を提供する。【解決手段】海面４に津波等の発生時に防波堤の破壊抵抗力を有し、放射性汚染水中のストロンチウムSr90などを吸着する防波堤構造において、防波堤の基盤捨石上のケーソン５と上部コンクリートの間に、Srよりイオン化傾向が大きいカリウムや水溶性カルシウムを含有するホルンブレンド「普通角閃石」等の大石２と小石３を部分的に積層し、引き潮時に海方向へ微弱に透過すると共に、満ち潮時には他端から海水を堤防内に導入する防潮堤防を形成する。多数の小石３はステンレス網(メッシュ)等などで包み、放射性汚染水中のストロンチウム９０などを吸着する交換可能な防波堤構造である。さらに、太陽光ガイド８で藻類が繁殖し放射性物質を吸収すると共に、放射線検出器９で海水中ベータ線を連続モニターする。【選択図】図１
