Alpha-irradiated cellulose acetate (T-Cellit) foils were exposed to 1.7 MeV electrons as well as to X-rays from a 60 kV Roentgen tube. These foils were then etched with solutions of various composition and temperature. The electron and X-ray irradiation caused marked changes in the bulk etching rate of the polymer and in the diameter of the alpha-particle tracks. These changes depend on the composition and temperature of the etchant as well as on the electron and X-ray doses. The possible consequences of the results are discussed.
