This work deals with the preparation of platinum nanoparticles using ionizing radiation - accelerated electrons with energy 4.5 MeV produced by linear accelerator Linac-4-1200 Tesla VT Mikroel. Aqueous solutions of platinum chloride with Triton X-100 as a reducing and stabilizing agent were used. Solutions were irradiated with doses up to 20 kGy in 20 ml glass vials. Solutions containing platinum ions were colored from yellow to black color after irradiation, depending of the dose. This points platinum ions reduction and nanoplatinum formation. Irradiated solutions were monitored by UV/VIS spectrometry, photon cross-correlation spectroscopy to determine particles size and distribution, transmission electron microscopy and X-ray diffraction analysis to provide information on the forms of prepared nanoparticles. The effects of PtCl4 and Triton X-100 concentrations and also dose deposited energy were studied.
