SAFETY CONSIDERATIONS IN THE HANDLING, DISMANTLING POST-IRRADIATION EXAMINATION AND DISPOSAL OF EXPERIMENTAL DEVICESGENERAL RECOMMENDATIONS9.1. The handling, dismantling and disposal of experimental devices or other irradiatedequipment that requires storage and eventual disposal in connection with the project should becarried out as per approved procedures.9.2. The procedures should take into account the safety evaluation of all operationsconnected with the handling, dismantling, post-irradiation examination and storage ordisposal of irradiated equipment. The activity and contamination of irradiated equipmentshould be evaluated in advance, under two assumptions:– the most probable course of the experiment; and– the worst possible combination of equipment failures and human errors.9.3. The radiological hazards should be assessed for all relevant conditions. The radiationprotection measures (e.g. shielding, cleaning of air, decontamination procedures and use of36
