The CANBERRA series of proportional detectors couple excellent detection efficiency with long detector life. CANBERRA manufactures both sealed and flow proportional large area detectors. They are used in hand and foot, whole body surface, and floor monitors, as well as in frisker applications along with a rate meter.

These detectors are also ideally suited in “hot particle” detection applications, as they can operate in elevated background fields (up to 10 mR/h ⁶⁰Co gamma) without saturating or swamping.
