APPARATUS AND PROCESS FOR THE QUENCHING OF THE RADIOACTIVITY OF RADIOACTIVE MATERIALS BY MEANS OF PIEZONUCLEAR REACTIONS INDUCED BY ULTRASOUNDS AND CAVITATION

摘要

The invention relates to an apparatus and a process for reducing the radioactivity of natural and/or artificial elements through piezonuclear reactions generated by means of insonation or sonication using an electromechanical transducer. The apparatus is characterised in that said electromechanical transducer comprises a stack of piezoelectric elements mechanically connected to a sonotrode of such a size as to operate at its own resonance frequency as a function of the electrical activation energy applied to said piezoelectric elements, to obtain the cavitation of the bubbles present in the liquid in which the radioactive substances are to be placed.
