The radiolysis of n-dodecane which is used both as diluent and as scrub solution and its physical property change were studied by irradiation from a <SUP>60</SUP>Co γ-source under the relative condition of the HA column in Purex process. First, the radiation exposure of organic phase in one pass through the HA columns were calculated by using the reference HA columns. Then, the radiolysis of the commercial n-dodecane without purification was investigated under the several dose conditions based on the absorption in one pass through the reference HA columns. A large variety of additional n-alkane degradation products was observed and they were increased with dose. The G-value in lower exposure was a high yield, and the absolute G-value decreased with increasing radiation exposure to 1.01W•h/l. Several expected inferable species from previous literature and three schemes for both principal radiolysis products and reaction of n-dodecane were suggested. These chemical products were probably formed in open system with gamma rays. The physical property change was also performed, and the effect of decomposition products on its change was small but not ignored. The annular with nozzle plates column diminished the absorbed dose in comparison with the other combination columns.
