Assessment of Very Low Aerosol Concentrations by Measuring the Unattached Fraction of 218Po
The correlation between the surface area of aerosols and unattached fraction of 218Po was studied and a simple relationship determined. A method is here proposed to measure small concentrations of aerosol particles, based on this correlation. This method offers an improvement in the uncertainties associated with detection of small aerosol concentrations because it relies on the detection of alpha particles, which can be done with low detection limits.
