摘要：

Synthesis of gold-palladium bimetallic nanoparticles using in situ radioactivity from Au-198 isotope is reported in this paper. Gold solution spiked with Au-198(III) has been mixed with PdCl2 solution in measured proportions in 50% polyethylene glycol solution. Au(III) and Pd(II) are reduced, and nanoparticles are formed due to radiolysis of the polymer solution. The solution has been characterized by UV-visible spectra, and the actual size has been determined using transmission electron microscopy in conjugation Midi energy dispersive X-ray measurements.
