| Abstract: | Three general filter materials cotton cloth 1, silk floss 1 and silk floss 2 for air sampling are introduced. Their filter resistance characteristic were measured at a wind tunnel.The filter efficiencies were measured by means of the radioactive aerosol method and the cloud samples collected by the rockets. |
