<p>PROBLEM TO BE SOLVED: To provide a method to effectively decontaminate forest, farmland, or the like which has been reluctantly neglected since a definite decontamination method has not been found.SOLUTION: An inorganic material adsorbent, such as zeolite, mordenite, smectite, and iou-seki, is pulverized to 1 to 1000 nanometers. The pulverizing material is dispersed in water as a colloidal matter. The colloidal matter is sprayed in a forest, soil, or the like contaminated with radioactivity so that a radioactive material is adsorbed.</p> |
