Measurement Control: A Case for Interlaboratory Sample Exchange Programs

Interlaboratory exchange programs are critical to a quality and reliable nuclear safeguards program. Use of standard methods is important in manufacturing, medical testing, forensic analysis, environmental monitoring and, of course, nuclear matefials accountability for s~eguards. Important decisions are oi-len based on the results of measurements. So high assurance and confidence through the use of standard and accredited procedures under undefiled conditions are critical. This paper will discuss the many benefits of interlaboratory measurement exchange programs in validating measurement performance and maintaining good measurement control.
