Performance Test and Evaluation at NUSTL (PTEN) Fact Sheet

The Performance Test and Evaluation at NUSTL (PTEN) program supports the nation’s need to detect and protect against radiological and nuclear threats by conducting functional tests of law enforcement radiation detection equipment before they are used by responders in the field. PTEN ensures equipment supplied to first responders works as designed and that all supporting materials are delivered. As a result of PTEN, first responders have increased confidence in their equipment because they know that each unit has been independently tested.
