Abstract In order to address the existing shortcomings associated with the radioactive measurement of marine fishes through the conventional way, e.g. massive amount of samples required, time-consuming and labor-intensive, an efficient and rapid pretreatment method was proposed and adopted to detect the level of Cesium-137 (137Cs) in Scomber Japonicus. In the application, the analogous activity of the 137Cs in the sample of Scomber Japonicus was measured at (0.072±0.01) Bq/kg-wet, which was within the margin of error of the measurement by the conventional method ((0.078+0.01)Bq/kg-wet). However, the new method achieved the reduction of 70% in processing time, and around 65% of amount of fish samples required.
