Deputy IAEA Director General Tero Varjoranta said that there have been over 40 instances of letting a country being inspected use their own nationals to do their own sampling and that the process is only a small part of a rigid regimen established by the agency to make sure there is no cheating.
He said the criteria at Parchin included: invasive monitoring by video and still cameras while the sampling took place; GPS tracking of the sampling process; IAEA agreement on where the samples were to be taken; review by unspecified peers of the inspection process; risk assessment and strict observance to make sure that procedures were followed step by step.
