Abstract. Laser ablation of metal nanoparticles in a solution containing radioactive nuclides, initiate their transformation into a stable state. This paper presents a brief review of studies of the dissolution of salts of radioactive uranium and cesium, where a significant acceleration of their decay is experimentally observed. Also it is proposed a possible mechanism of suppression of radioactivity, for example, salts of cesium. The obtained results allow us to hope for the establishment of effective technologies for disposal of liquid radioactive wastes containing cesium-137 and other dangerous isotopes.
Keywords: copper vapor laser, gold nanoparticles, laser ablation, radionuclides
