METHOD FOR PRODUCING FIRED PRODUCT
PROBLEM TO BE SOLVED: To provide a method for producing a fired product that produces a fired product having reduced radioactive cesium concentration by subjecting an object to be treated to an appropriate heating treatment in accordance with a radioactive cesium concentration of a radioactive cesium-contaminated object to be treated so as to produce a fired product usable in an appropriate application.SOLUTION: The method for producing a fired product includes a cesium concentration measurement step of measuring a radioactive cesium concentration contained in an object to be treated and a heating step of adjusting its components of the object to be treated to produce an object to be heated or producing an object to be heated without adjusting its components and then heating the object to be heated and volatilizing the radioactive cesium to produce a fired product. After the cesium concentration measurement step, the application of the fired product is determined by selecting from among a plurality of applications including at least the application to a cement clinker and the application to an earthwork material in accordance with the radioactive cesium concentration and the object to be heated is prepared in accordance with the application of the fired product.SELECTED DRAWING: None
【課題】放射性セシウムで汚染された処理対象物の放射性セシウム濃度の大きさに合わせて、該処理対象物について、適切な用途に用いうる焼成物が得られるように、適切な加熱処理を行って放射性セシウム濃度が低減された焼成物を得る焼成物の製造方法を提供する。【解決手段】処理対象物中の放射性セシウム濃度を測定するセシウム濃度測定工程と、処理対象物を、成分調整せずにまたは成分調整して、加熱対象物を得た後に、該加熱対象物を加熱して放射性セシウムを揮発させ、焼成物を得る加熱工程を含み、セシウム濃度測定工程後に、放射性セシウム濃度によって、焼成物の用途を、少なくともセメントクリンカの用途及び土工資材の用途を含む複数の用途の中から選択して定め、焼成物の用途に応じて加熱対象物を調製する焼成物の製造方法。【選択図】なし
