Abstract  

Isotopic ratios of240Pu/239Pu in environmental samples can provide improtant data for identifying and confirming contamination sources. One low cost alternative for performing this analysis uses a combination of high resolution alpha-spectroscopy and spectrum analysis software. This method uses unmodified, commercially available equipment and software. Plutonium alpha-spectra were gathered with an alpha-spectrometer system set up for low-level actinide determination. Experimental spectra were imported into a commercially available data analysis program, and fit with mathematical descriptions of alpha-peaks using the Marquardt-Levenberg algorithm. The spectra was then deconvoluted into its239Pu and240Pu components and the activity ratio was calculated.
