The Austral-Rad Personnel Portal/Mobile Monitor has been specifically designed to meet the Federal Emergency Management Agency (FEMA) standard requirements.The unit consists of two Beta and Gamma detectors which are enclosed within a tough, durable casing thus ensuring there is no need for additional weather proofing or protection. The units works by performing a quick scan of the user once they are positioned between the two portal monitors. The unit then provides confirmation of contamination through both an audible and visual signal.
