1° Verify that the person concerned needs, in the course of his or her activity, to have access to ionising radiation sources or batches of category A, B or C radioactive sources, to transport them or to have access to information relating to the means or measures implemented to protect them against malicious acts;
2° May request in writing the opinion of the Minister of the Interior or the authority designated by the Minister of Defence for activities falling within the latter’s remit.
