PROBLEM TO BE SOLVED: To provide facilities where cesium is efficiently decontaminated from a treated object such as soil and the size of an object contaminated with cesium is reduced.SOLUTION: A decontamination apparatus 100 comprises: a heating furnace 210 in which a treated object SCs is heated to be the boiling point or higher of cesium and cesium vaporizes from the treated object; a cooling part 310 for cooling the vaporizing cesium; and an adsorption part 410 containing an adsorbent A adsorbing cesium to make the cesium cooled by the cooling part 310 adsorb to the adsorbent A. 【課題】土壌等の処理対象物からセシウムを効率よく除染するとともに、セシウムに汚染された対象物を減容化する設備を提供する。【解決手段】除染装置１００は、処理対象物ＳＣｓをセシウムの沸点以上に加熱し、当該処理対象物からセシウムを気化させる加熱炉２１０と、気化したセシウムを冷却する冷却部３１０と、セシウムを吸着する吸着材Ａを内在させ、冷却部３１０によって冷却されたセシウムを当該吸着材Ａに吸着させる吸着部４１０と、を備える。【選択図】図１
