Radiation dose absorbed in the organic extractant was estimated for the counter-current extraction with mixer-settler in the partitioning of the high-level liquid waste of fuel reprocessing. The radiation dose due to the absorption of α- and β-particles was calculated to be 10, 5.0 and 0.42 Wh/<I>l</I> for 150 days, 1 year and 10 years after fuel discharge from the reactor, respectively. About 70-90% of the total dose was due to the absorption of β-particles. These values were discussed in comparison with the published data for the fuel reprocessing. On the basis of the calculated data, the radiolytic effects upon the extraction of strontium, lanthanoids and transplutonium elements in partition-ing were estimated be sufficiently small.
