This paper relates to an experiment of removing aerosols using a radiation effect by γ-ray with a TRAPOL (trapping of aerosol by pole) in Ar-gas stream. If either positive or negative ions produced by the radiation are caused to act on aerosol, the aerosol charge becomes unipolar. The charged aerosol is trapped on an electrode of the opposite polarity, and removed onto HEPA filter with a high efficiency. The DF (decontamination factor) in TRAPOL exceeds to 103 in a particle range above 0.4 μm, and the DF of HEPA filter is improved upto 1,000 times compared with the inherent DF value of the filter, where DF is defined as the ratio of particle number concentrations at the entrance to those at the exit.
