Throughput: Although manufacturers of WTMDs may specify a device throughput (i.e., number of people that can be scanned per unit time), overall throughput is affected by the experience of the operator, the arrival rate of people, the compliance and preparation of people to be scanned (e.g., removing metal items as they approach the detector), and the availability of personnel and equipment to adjudicate alarms.
On average throughput is 20 persons per hour, just like their scanner. That is one person every 3-seconds.
