Safety & Radioprotection

Safety & Radioprotection WP5 within EURISOL List of objectives: “In the framework of this task calculation of radiation production and activation should be performed. The methods for shielding against prompt radiation and for the containment of activity should be studied. This task also should investigate the handling of targets and in particular the disposal of spent targets. The conformity of the proposed installation to the legislation shall be insured”.
