Method and apparatus for decontaminating substances contaminated with radioactivity |
摘要 |
A method of effectively decontaminating a substance contaminated with radioactivity, in particular, shot blasting grit contaminated with radioactivity, and a decontaminating apparatus which makes it possible for a single apparatus to perform all of the decontamination processes without moving the contaminated substance from one apparatus to another for each process, thereby realizing reduction in the installation space and achieving an improvement in operational efficiency. The method comprises: decontaminating a contaminated substance by washing it with achelate liquid; draining the chelate liquid; raising the temperature of the substance to a level not lower than the boiling point of a solvent by means of hot air; supplying the solvent to the substance to result in rapid vaporization thereof; removing the remaining chelate fluid liquid by the force of this vaporization and draining the same;and drying the substance.
