The organics in gamma-ray irradiated aqueous N, N-diethylhydroxylamine (DEHA) solution, which is used as a reducing agent in reprocessing spent nuclear fuel, were analyzed with gas chromatography equipped with FFAP capillary column and flame-ionization detector. It was found that irradiated DEHA solutions contained acetaldehyde, ethanol, and acetic acid. For DEHA of 0.2 mol/L irradiated to 10 similar to 1000 kGy, the concents of acetaldehyde, ethanol and acetic acid are (9.7 similar to 18.7)x10(-3), (0.4 similar to 23.4)x10(-3) and (6.5 similar to 11.7)x10(-3) mol/L, respectively. The concentration of DEHA decreases obviously with the dose.
