摘要：
A radiography technique which makes use of alpha-particles as penetrating radiation has been developed. The images were registered in the solid-state nuclear track detector CR-39 and the conditions to obtain the best radiography image were 2.2 h of irradiation and 25 min of etching in a KOH (30%) aqueous solution at 70 degrees C. For such conditions the resolution in the image was 23 mu m. Some radiographs are shown and demonstrate the potential of the technique to inspect samples with thickness in the mu m range.
