Abstract
This paper presents a wide range of experimental results of prompt and delayed components of the conductivity induced by x-rays in Mylar (PET) and Kapton (Polyimide). Measurements were carried out under a vacuum at room temperature. They were made for a large range of parameters: electric field E (104 to 4.8X105 V/ cm); exposure rate X (85 to 550 R/ s); and thickness d of the sample (6 to 75 ¿m). Electrodes were made of evaporated aluminum, but in some measurements gold was used. Gold increased the exposure rate, due to its high er atomic number. Finally, a study of the recovery of the irradiated samples was made.
