| A one or two sided system can be positioned in front of customs officers' or immigration officials' desks or at any common entrance or exit in the customs area. Passengers with their luggage will have to move through these portals and the presence of Pu can be determined. These monitors can also be mounted on existing metal detectors and provides a local visible or audible alarm. A single panel with a nominal source to detector distance of 50 cm can detect 10 grams of Pu metal or 20 grams of Pu oxide in less than 1 second. Higher sensitivity models are also available. |
