The Aptec-NRC series of proportional detectors couple excellent detection efficiency with
long detector life.
Aptec-NRC manufactures both sealed and flow proportional large area detectors. They are
used in hand and foot, whole body surface, laundry and floor monitors, as well as in frisker
applications along with a rate meter. These detectors are available in size from 56 cm
2
up to 800 cm
2. They have either fixed or detachable mesh protection and come with either MHV or D type connectors. (Note that certain sizes are specific to either flow or sealed).
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.
Sealed detectors come with a 4.5 mg/cm2 titanium window and are best for beta detection. They have all the advantages associated with not requiring a P-10 gas supply (mobility, no purging, no bottle changing, etc.). Sealed xenon are ideal for isotopes used in nuclear
medicine (e.g. 125I). Flow proportional detectors come with an ultra thin 0.8 mg/cm2 mylar window and are the detectors of choice for simultaneous alpha and beta detection.
