An experimental study has been conducted in order to assess the performance achievable with an instrument based on the method of x-ray differential absorptiometry aimed at the determination of the Pb content of standard aerosol sampling filters. The method, described here, relies on the transmission of photons of two energies, properly chosen in the 10-15 keV range. The principles and basic features of the instrumental approach are discussed on the basis of experimental data and an evaluation of the performances achievable is given.

Abstract
An experimental study has been conducted in order to assess the performance achievable with an instrument based on the method of x-ray differential absorptiometry aimed at the determination of the Pb content of standard aerosol sampling filters. The method, described here, relies on the transmission of photons of two energies, properly chosen in the 10-15 keV range. The principles and basic features of the instrumental approach are discussed on the basis of experimental data and an evaluation of the performances achievable is given.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
