摘要：

A method for the measurement of organically bound tritium (OBT) in marine biota has been developed using a combustion device designed with three independent temperature control zones and a two-stage intake mode to ensure full combustion of samples. The versatility of the combustion device and combustion water recoveries were tested on nine different types of marine biota, with recoveries varying from 85.15% to 92.67%, with an average of 89.4 +/- 11.34%. This indicates that our developed combustion method (combustion program and apparatus) provides stable results. Finally, the OBT activity of the marine samples measured varied from 1.88 to 12.9 Bq/L, with an average of 5.61 +/- 3.21 Bq/L.
