[en] The decomposition of PCP in water induced by γ-irradiation has been studied at low PCP concentration under various conditions. PCP is consumed linearly with increasing absorbed doses. PCP could be decomposed almost completely by γ-irradiation at relatively high doses. Chloride ions are increased simultaneously with the consumption of PCP. The amount of chloride increases also linearly with the increasing absorbed dose. At relatively high absorbed dose, almost all chloride atoms in PCP are eliminated. Chemical oxygen demand (COD) has been measured after irradiation. Ozone is a powerful oxidizing agent for PCP. After saturation of 1.09x10-4 mol.dm-3 PCP aqueous solution with ozone, PCP concentration drops to 1.6x10-5 mol.dm-3. The combination of ozonation-ionizing radiation treatment is very effective, which greatly decreased the dose needed. pH and chemical oxygen demand also have been measured after ozonation and irradiation
