This paper compares the general properties of a chinesemade cellulose nitrate and two kinds of cellulose acetate films with different thickness in discriminating α particles from protons. The 140 µm cellulose acetate film has finally been selected as the solid state track detector used in nuclear lifetime measurement by the blocking effect.
