"In December 2016, the System Assessment and Validation for Emergency Responders (SAVER) Program conducted an operationally oriented assessment on portable radiation portal monitors (PRPMs). Five PRPMs operating in pedestrian scanning mode were assessed by emergency responders at the Brookhaven National Laboratory in Upton, New York. The criteria and scenarios used in this assessment were derived from the results of a focus group of emergency responders with experience using PRPMs. The assessment addressed 25 evaluation criteria in four SAVER categories: Capability, Deployability, Maintainability and Usability."
