Verification Sampling Techniques in a Safeguards Situation

Verification sampling techniques in a safeguards situation are used to detect whether the assigned amount values on materials of strategic importance are, within the limits of statistical measurement variation, correctly stated. If they are not, the statistical evidence of verification is used to signal an investigation into the causes of the anomalies and discrepancies. Such an investigation is designed to see if there is prima facie or highly corroborative evidence of diversion and/or of attempts to conceal diversion. The main characteristics which the verification techniques should have is that they be adequate, robust and efficient against those diversion techniques which may be used to accomplish and/or to conceal diversion. A terminology which has gained currency here is to call the inspection agency the inspectorate.
