摘要

An alpha spectrometry combined with a filter sampling method has been applied for the measurement of radioactive aerosols. The Nuclepore membrane filter was used for the aerosol sampling, and its collection efficiency was experimentally determined. Examples of measured Po-218 concentrations in three rooms were given.
