Pulsed radiolysis, EPR, and optical spectroscopy were used to investigate the radiation-induced reduction of Hg 2 2+ ions in aqueous solutions. It was shown that the Hg 2 + ions that form as a result of the reduction reaction react rapidly with Hg 2 2+ with formation of Hg 4 3+ . Constants of formation and disappearance of these ions were determined. The process of disappearance of this species results in the formation of more complex clusters containing six or more mercury atoms. Further complication of the clusters affords colloidal metal particles.
