Electrets are prepared from pure parraffin wax by irradiation with β‐rays followed by formation in a constant electric field. The charge of the electrets is measured by means of the inductive method and with Faraday cylinder. The dependence of the electret charge on intensity of forming field, forming time, irradiation time, and storage time after irradiation, and the permanence of the charge, are investigated. Electrets prepared in this way have charges of the same order of magnitude as thermic electrets made from carnauba wax and formed in similar forming fields.
