Activation of thick targets by energetic heavy ions and the resultant radiation levels.
This study completes data collected for thick targets exposed to carbon and oxygen ions accelerated at 86 MeV/u. The radioactivity induced in carbon and tungsten targets bombarded by argon projectiles at 95 MeV/u has been studied in order to assess the relative contributions of the incoming heavy ion and the mass number of the bombarded nuclei to the consequent radiation hazards related to the production of radioactive ion beams. Induced radioactivity measurements are only rarely made under controlled irradiation conditions, in order to derive from the measured activities the dose rates after beam bombardment and a prediction of radiation protection constraints.
