Description
In order to obtain the radioactivity concentration information of the nuclides in the process of disposal of low level waste, an analytical method for the determination of 55Fe in spent ion-exchange resin was established by using TRU resin as the separation and purification material and liquid scintillation spectrometry method. The chemical recovery of Fe for this method is approximately 87.23%, and the minimum detectable specific activity is approximately 11.43 mBq/g. (authors)
