238Pu spike for the determination of concentration of Pu by isotope dilution techniques-feasibility analysis. CP-17

Determination of concentration of Plutonium is required due to its strategic importance as well as for nuclear material accounting. Since Pu is highly radio toxic, its determination in a variety of environmental matrices is extremely necessary. Isotope dilution techniques are usually preferred since the quantitative separation of the element of interest is not warranted for and hence can be employed for complex matrices such as those encountered in environmental samples. Two isotopic dilution techniques employed for the determination of Pu concentration are Isotope Dilution Mass Spectrometry (IDMS) and Isotope Dilution Alpha Spectrometry (IDAS)
