摘要：

A method based on wet oxidation method was developed for determining 3H and 14C in the radioactive waste resin produced from nuclear power plant. The affecting factors of method recovery were analyzed, and the 3H and 14C in the waste resin from a domestic nuclear power plant were measured. The results show that the concentration of H2O2 has the greatest influence on the recovery of the method. The minimum detectable specific activity for 3H and 14C is 41 Bq/g and 1.3 Bq/g, respectively. There is no significant difference between the measurement results of 14C and that of Analysis method of 14C in biological samples-Oxgen bomb combustion method (GB/T 37865-2019), the measurement precision of 14C is 10.2%. The average specific activity of 3H and 14C is (6 134±640) Bq/g and (2 724±147) Bq/g in the waste resin of a domestic nuclear power plant. © 2021, Editorial Board of Atomic Energy Science and Technology.
