АТ930 Pedestrian Radiation Monitor Purpose AТ930 Pedestrian Radiation Monitor (PRM) operates in a continuous automatic control mode and is designed to detect sources of gamma radiation in a stream of pedestrians. ▪ Radiation control in pedestrian traffic: - In public places and institutions - In airports, bus terminals, railway and underground stations Conformance to international standard IEC 62244:2006 - At access control points on nuclear industry objects Radiation protection instrumentation – Installed radiation monitors for the detection of radioactive and special nuclear materials at national borders Features ▪ Rapid accommodation to changed radiation background ▪ Sound and light alerts are emitted when the threshold levels are exceeded ▪ Mobile and capable of creating safety lanes ▪ Self-testing of components during operation ▪ Continuous and occasional radiation monitoring ▪ 230V-50Hz mains/integrated battery operation Operating principle Pedestrian Radiation Monitor is based on a smart gamma radiation detection unit. PRM powers on and automatically enters natural gamma background measurement mode. The result of measurement is used for calculating and setting the threshold gamma radiation level – an alarm level. When a pedestrian crosses the control zone border, the PRM switches to continuous gamma radiation measurement mode, calculates the count rate and compares the measured values to alarm threshold level. When obtained data exceeds the set alarm threshold level, the monitor activates audio and visual (red light) alarm to inform the staff (security guard) of a gamma radiation source detection. Additional base for operation without anchoring to the floor INSTRUMENTS AND TECHNOLOGIES FOR NUCLEAR MEASUREMENTS AND RA
