N, N-diethylhydroxylamine (DEHA) is a novel salt-free reducing reagent used in the separation of Pu and Np from U in the treatment of used nuclear fuel. This paper reports on the radiation damage and radiolytic by-product of 0.5 mol L⁻¹ DEHA in 0.3 mol L⁻¹ ~ 1.0 mol L⁻¹ HNO₃ at dose up to 25 kGy. Results show that the radiolysis rate of DEHA is less than 10%. The main radiolytic products are hydrogen, acetaldehyde, acetic acid and nitrous acid, which increase with the dose. The concentration of acetaldehyde and acetic acid is much higher than that of nitrous acid.

低剂量 HNO3 中 N, N- 二乙基羟胺的辐解和辐解副产物

N,N-二乙基羟胺 (DEHA) 是一种新型无盐还原剂，用于在废核燃料处理中从 U 中分离出 Pu 和 Np。本文报道了在剂量高达 25 kGy的 0.3 mol L ^-1  ~ 1.0 mol L ^-1 HNO _{3中，0.5 mol L} ^-1 DEHA的辐射损伤和辐射分解副产物。结果表明，DEHA的辐解率小于10%。辐解产物主要有氢气、乙醛、醋酸和亚硝酸，随剂量增加而增加。乙醛和乙酸的浓度远高于亚硝酸。
