My experience with measuring plutonium 239 in urine was highlighted 
by the difficulty of accurately measuring small concentrations using 
complex chemical separations, isotopic tracers, often inefficient 
electro-deposition, and hours of counting based on alpha particle 
spectra.  I believe the mass spectrometric methodology is much more 
accurate and the choice of preference for future work.
