Title:
MATERIAL AND METHOD FOR FIXING RADIOACTIVE IODINE
Document Type and Number:
Japanese Patent JP3393916
Kind Code:
B2
Abstract:
PURPOSE: To obtain iodine fixed matter stable over a long period of time while improving the adsorbability of radioactive iodine.
CONSTITUTION: A cementitious hydraulic fixing material high in the adsorbability of radioactive iodine consists of 50-100% of a hydraulic inorg. compd. and the remainder of fly ash. This fixing material is brought into contact with radioactive iodine contained in a soln. and a radioactive iodine adsorbed substance is taken out by solid-liquid separation to obtain iodine fixed matter.
