Quantification of curium isotopes in environmental samples: drawbacks, speciation and specific tracer

In this study, drawbacks of the use of 243 Am as a tracer in order to quantify curium isotopes during a complex chemical procedure were highlighted. These drawbacks were investigated through a speciation computation simulation based on the compilation of over 50 stability constants. A new curium sta...

Zusammenfassung:In this study, drawbacks of the use of 243 Am as a tracer in order to quantify curium isotopes during a complex chemical procedure were highlighted. These drawbacks were investigated through a speciation computation simulation based on the compilation of over 50 stability constants. A new curium standard was then characterized and used to quantify a wide 244 Cm activities range in environmental samples. Obtained results were in excellent agreement with spiked activities and more consistent than those obtained when using 243 Am as tracer.
