高效预处理方法在海洋鱼类137Cs测量中的应用

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%.

An efficient method for the rapid measurement of radionuclides

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.
