Abstract:
Experimental data are presented on the laser-induced beta decay of caesium-137. We demonstrate that the exposure of a gold target to a copper vapour laser beam (wavelengths of 510.6 and 578.2 nm, pulse duration of 15 ns) for 2 h in an aqueous solution of a caesium-137 salt reduces the caesium-137 activity by 70%, as assessed from the gamma activity of the daughter nucleus 137mBa, and discuss potential applications of laser-induced caesium-137 decay in radioactive waste disposal.
Keywords:
copper vapour laser, gold nanoparticles, laser ablation, beta decay, radionuclides.
