Study on Fast Measurement of Radioactive Cesium in Seawater
Abstract: The activity concentration of radioactive cesium in seawater must be measured by adsorption concentration, and the time to shorten the concentration of adsorption is the key factor to improve the spatial and temporal resolution of sampling. Research group surveyed the coastal waters of Xiamen in July and November 2014, using the precipitation method and the on-site rapid enrichment method respectively for the measurement of radioactive Cs-137 in sea water samples, and aimed at the volume, the results error and method detection limits were investigated. The results show that the results obtained by the two methods were at the same magnitude level, the consistent rate being 66.7% in the July 2014 voyage and 46.7% in November 2014. When the volume is less than 1000 L, the error of the data and the detection limit of the method are obviously decreased with the increase of the volume, so that the volume of filtered seawater should not be less than 1000 L using the on-site rapid enrichment method.
