Development of a so-called hour method for analysis of plutonium in soil samples
- 1. Instituto de Radioprotecao e Dosimetria (IRD), Rio de Janeiro, RJ (Brazil)
Description
Following the definition from the International Atomic Energy Agency, a so-called hour method is that which needs six hours time interval from the sample solution preparation to the data evaluation. Two alternative procedures to be applied to soil samples were studied. One based on LaF3 precipitation and ion-exchange and another on extraction chromatography with TOPO/Silicagel. Both methods gave good results in terms of accuracy, chemical yield and time requirement, but the extraction chromatographic procedure is recommended because it involves fewer steps.
