"The System Assessment and Validation for Emergency Responders (SAVER) Program will conduct a comparative assessment of portable radiation portal monitors (PRPMs) to provide emergency responders with information that will assist with making operational and procurement decisions. As a part of the assessment process, a focus group met in March 2016, with the primary objectives of recommending evaluation criteria, product selection criteria, products, and possible scenarios for the assessment of PRPMs. PRPMs are used by police, security, and emergency response personnel to screen people for the presence of radioactive materials. These devices may be used to screen large populations for contamination after a radiological or nuclear incident, or to screen people entering or leaving a sensitive area. The PRPMs assessment will be conducted by emergency response professionals based on the recommendations presented in this report."
