Comment:
The concentration profiles of 210Pb were determined through the measurement of 210Po in radioactive equilibrium at Edith Cowan University. The concentrations of 137Cs were determined by gamma-ray spectrometry (Canberra Be3830) with a relative counting efficiency of 35% and an energy resolution of 1.8 keV (at 1332 keV).
