It was found that irradiated DEHA solutions contained acetaldehyde, ethanol, and acetic acid. For DEHA of 0.2 mol/L irradiated to 10~1000 kGy, the concents of acetaldehyde, ethanol and acetic acid are (9.7~18.7)×10-3, (0.4~23.4)×10-3 and (6.5~11.7)×10-3 mol/L, respectively. The concentration of DEHA decreases obviously with the dose.展开更多
