Standard Operating Procedures (SOP) for random checking of imported consignments of metal scrap with respect to radioactive contamination
Show AI Summary
Radioactive contamination checks require preset alarm-based monitoring, isotope identification, and mandatory notification and repatriation measures.
Random radiation screening of imported metal scrap requires verification of a Pre-Shipment Inspection Agency certificate and importer-exporter assurance, measurement of background and container surface radiation with handheld monitors set to a preset alarm above background, and comparison with PSIA certificates or self-declarations. Exceedance of the alarm mandates isotope identification: NORM findings permit release; identification of other radionuclides requires immediate notification to nuclear emergency authorities, relocation to a cordoned area with monitoring and reporting, and initiation of repatriation or deportation, with costs borne by the importer or designated responsible person.
