Abstract
Laser-light effects on γ-activities of the 137Cs and 134Cs water solutions containing gold nanoparticles are investigated at laser-light intensity on the order of 1012 W/cm2. The irradiation is found to reduce the radioactivities of both nuclides. Over the period of irradiation, no enhancement of the γ lines of spontaneous decays is detected. Possible mechanisms of the observed effect are discussed.
