This work assessed ball-milling treatment for remediation of cesium (Cs)-contaminated soil. The immobilization efficiency increases from 56.4% in the absence of treatment to 89.9, 91.5, 97.7, and 96.4% when the soil is ball milled for 30, 60, and 120 min, respectively. However, the addition of nanometallic Ca/CaO and NaH2PO4 increased the immobilization efficiency to approximately 96.4% compared with ball milling alone, even when the milling time was decreased to 60 min. Actually, with the addition of Ca/CaO and NaH2PO4, the leachable fraction of Cs was reduced in the soil after a short milling time. These promising results suggest that ball milling can be regarded as applicable for the remediation of cesium-contaminated soil in dry and water-free conditions. This treatment method requires no expensive reagent and does not generate exhaust gases. It requires only electricity with cheap and commercially available reagents. This treatment process is an environmentally friendly depollution technique ©2013 American Society of Civil Engineers.
