Are studied the kinetic of the decomposition of 2, 3, 7, 8-tetrachlorodibenzoparadioxin (TCDD) in water solution and in damp plant products under the action of ionizing radiation of 60Co. The values of the radiation-chemical yield of the decomposition of TCDD in the solutions are (0.3…1.5)∙10-5mol./100 eV (for solutions with concentrations of TCDD 0.2…2 µg/l in open reaction cell) and in the air-bubbled solution 2.4∙10-5 mol./100 eV (for a solution with a concentration of TCDD 2 µg/l). The absorbed dose of ionizing radiation equal to 25 kGy, in the presence of molecular oxygen leads to a decrease in the studied quantities of TCDD practically to zero. © 2015, National Science Center, Kharkov Institute of Physics and Technology.
