Abstract
A new protocol for the rapid quantification of actinides (U, Th, Pu, Am and Np) and Sr in soil samples has been developed. This protocol includes three steps: (1) an alkaline fusion digestion, (2) an automated separation and (3) an on-line ICP-MS measurement. Eluted fraction containing strontium can be collected to quantify radiostrontium using off-line radiometric techniques. After an optimization of the separation protocol using a design of experiments, excellent figures of merit are achieved. These figures include high chemical recoveries (>80%) for all radionuclides investigated, low quantification limits for actinides and concordance between measured activities and reference values. This protocol allows the automated treatment (sample dissolution included) of up to 10 samples in 24 h. [ABSTRACT FROM AUTHOR]
