A new cellulose-glass fiber filter paper (HE-40TA) was produced on a trial basis to improve the collection efficiency of Toyo HE-40T filter paper, which is widely used for sampling of radioactive aerosols at nuclear facilities in Japan. HE-40TA filter paper was tested for collection efficiency, pressure drop and mechanical strength.<br>It was observed that the collection efficiency of HE-40TA was more than 87%, under the conditions of this study: the face velocity from 20 to 130cm/s, the size of DOP aerosol from 0.07 to 1.0 μm in diameter. The pressure drop of HE-40TA filter paper was about 1.2 times higher than that of HE-40T. And the mechanical strength of HE-40TA filter paper was sufficient for practical use.
