摘要针对传统海洋鱼类放射性测量过程中样品需求量大、预处理耗时长、劳动强度大等问题，本研究提出了一种高效快速的预处理方法，并将其应用于日本鲭体中放射性核素¹³⁷Cs的测量.研究结果显示，利用该预处理方法所获取的日本鲭样品中¹³⁷Cs的活度值为（0.072±0.01） Bq/kg鲜样，与用传统方法测量所获得的结果（0.078±0.01） Bq/kg鲜样处于误差范围以内，但样品的预处理时间可缩减约70%，样品量也减少约65%.

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.
