N2 - The angular and energetic distribution of alpha particles from the 222Rn chain in air incident on a detector have been determined by the Monte Carlo method. Stopping power of alpha particles in air have been taken from the ICRU49 report. The incident alpha-particle spectrum was found for various equilibrium factors. It has been shown that the spectrum between 5.5 and 7.69 MeV depends on the equilibrium factor. High resolution alpha spectrometry can enable the measurements of concentrations of 214Po and 218Po in air. The maximal sensitivity coefficient has also been determined for measurements of 214Po concentrations. © 2002 Elsevier Science B.V. All rights reserved.
