The use of pesticides in agriculture presents some problems to ecosytems as a consequence of their remaining in the environment. Conventional methods for environmental decontamination sometimes just transfer these residues from one place to another. The use of gamma radiation from cobalt-60 to induce 2,4-D degradation in aqueous solution containing humic acid was studied. Results show that the herbicide is completely degraded after treatment with a 30 kGy dose. There were decreases in the degradation of the 2,4-D when humic acid was added at all doses. Some radiolytic products are proposed. The 2,4-D radiolytic yields (G) from 2,4-D were calculated.
