AmCamOVERVIEW
Cavendish Nuclear’s AmCam is a handheld, compact, lightweight device thatcombines a gamma ray spectrometry detector with a small video camera, capable ofindicating radiation count rate alongside a corresponding video image of the area
being surveyed.

KEY INFORMATION• Quick identification of the location of materialbuild up within gloveboxes• Images can be used to pinpoint the origins ofelevated dose / count rates• Estimates can be made of the dose rates andactivity levels of hotspots• Aids quality assurance for the Post Operations
Clean Out (POCO) characterisation or waste
category segregation processes• Used to plan / target future POCO clean-up
operations• Used to segregate waste items between PCM andILW waste categories** subject to an appropriate calibration andsuitable robust operating procedureswww.cavendishnuclear.com

OUR PRODUCT IN DETAIL
The system is designed to establish,
visualise and measure in real-time thelocations of plutonium, by measuring
the low energy 60keV gamma radiation
emitted from Americium-241 (241Am),a daughter product of plutonium-241(241Pu). The system has been optimisedso that the video camera and Cadmium
Zinc Telluride (CZT) gamma ray
detector, within a thin lead collimatorassembly, are aligned coaxially. The
collimation of the detector is designed
such that the field of view of thedetector exactly matches the field ofview of the video camera. This allows
the system to provide an indicationof the radiation count rate from thedetector along with video image ofthe exact area where the radiation wasemitted.
A live video stream can be viewed on
a computer screen, consisting of a large
central video image from the camera
with the count rate from the source ofany radiation measured by the detector.
The output of the AmCam is constantly
updated in real time throughout theduration of the scan. Video and countrate data are recorded in MP4 format
for offline viewing.
A count rate bar and numerical display
showing counts per second are also
provided to indicate the count rate
being recorded from the area or item
being shown in the video image. Thiscount rate information is also updated
in real-time. In addition to the visualindication of count rate from thecurrent field of view of the device, thesoftware also provides the operator
with an audible indication of thecurrent count rate using “Geiger clicks”,
the frequency of which increases as
the count rate rises. This feature isimportant because the operator’s
attention will often be focused on theAmCam device rather than on thecomputer or tablet screen.

Features• Compact, lightweight, handheld
device.
• Deployable inside gloveboxes using
the custom designed AmCam glove
port bag.
• Real-time updated video and countrate data.

• Measures in real-time the low energy
60keV gamma radiation emitted
from 241Am.
• Video and count rate data arerecorded in MP4 format.
• A count rate bar and numericaldisplay showing counts per second.

AmCam display screens showing (top) field of view with no sources present within FOV and indicating low
count rate and (bottom) a higher count rate due to the presence of a plutonium sample on the extreme
right of the FOV.
