| Abstract: | This work studies the alpha particle radiography technique in conjunction with the CR-39 SSNTD. The irradiations were made in the CV-28 cyclotron at IEN/CNEN/RJ using a 7 MeV/nucleon alpha particle beam. The best etch time to obtain radiographs was determined as six hours. A calibration curve was obtained, so to allow a quantitative interpretation of the images to be performed. Its behavior was checked by several experiments with other energy degrading materials. Several radiographs of “in-vitro” biological specimens were obtained. The results showed the potential capability of this technique for studies in paleontology. |
