In this work, the 0.1–0.5 mol·L^–1 N, N-dimethylhydroxylamine (DMHA) were irradiated to 5–25 kGy, and gaseous products of mainly hydrogen, methane, ethane and n-butane were measured by gas chromatography. The results show that the volume fraction of hydrogen and methane increases with the concentration of DMHA and dose, and the latter does not change markedly at high doses.
