Investigation on the chemical recovery and stability of a newly developed method for < sup > 137 < /sup > Cs measurement in marine biota Scomber Japonicus

Appl Radiat Isot. 2022 Jul 19;188:110381. doi: 10.1016/j.apradiso.2022.110381. Online ahead of print.ABSTRACTSeven sets of experiments based on a newly developed Mincing-Digesting method for 137Cs measuring in marine biota Scomber Japonicus were conducted to investigate the method's stability and chemical recovery. The results show the chemical recovery of radiocesium for aqueous parts is 68.77 ± 11.2%, which is relatively stable with R2 = 0.97, means this value could be used when measuring the Scomber Japonicus or other marine biota belonging to the same category and having similar muscular tissue and cellular structure. Meanwhile, the Minimum Detectable Activity (MDA) of the method is 0.013Bq/kg-ww which is comparable with that of the conventional method, means that the method could be further developed as a reliable and efficient way to measure other radionuclides in other marine biotas in the future if more experiments were conducted.PMID:35872558 | DOI:10.1016/j.apradiso.2022.110381
