The influence of typical *OH radical scavengers as potassium formate and isopropanol on the radiation-induced removal of lead was individually studied. The lead can be completely removed from aqueous solutions containing 1x10(-2) mol/L of formate already at the dose of 2.5 kGy. With increasing concentration of formate (5x10(-5)-1x10(-2) mol/L) increases the amount of Pb(formate)(+) species in the solution before irradiation. The radiation product is metallic lead at low concentration of formate to PbCO(3) at higher concentration of scavenger. In the system with 10% isopropanol dominates the species Pb(2+) and the product of radiation reduction is then metallic lead.
