DESCRIPTION
The iCAM intelligent alpha beta continuous air monitor forms part of the CAMSYS™ product line. It provides robust and reliable monitoring of airborne alpha and beta particulate activity in the workplace. It acts as a simple alarming monitor for operators, while measuring airborne activities in real time with the sophistication required to provide low false alarm rates and high protection levels. At the same time it provides automated facilities which assist supervisors to conduct detailed setup and operational overview.
The iCAM monitor measures airborne alpha and beta particulate activity with dynamic radon/ thoron alpha and beta background compensation. It also provides static or dynamic compensation of beta measurements for gamma background depending on the choice of detector type.
The iCAM unit has high detection efficiency for both alpha and beta particles and provides good sensitivity for low energy beta detection down to 50 keV.

DESCRIPTION
The G64 area gamma monitor forms part of the CAMSYS product line. It is a compact, mainspowered, microprocessor-based radiation monitor, designed specifically for area and process monitoring in nuclear facilities. Its main functions are to display the gamma dose rate in the area and to warn local personnel in the event of an alarm situation.
The G64 instrument is intended for installed use but can also be used on a bench stand or wheeled trolley to provide temporary monitoring or to supplement permanently installed monitors during maintenance activities.
The standard G64 monitor is supplied with a compact solid state detector for use in low to medium dose rate applications, but it is also available in three other versions for additional applications:
G64IC™ monitor: for high dose rate and high integrated dose applications
G64SC™ monitor: intended for use with existing scintillation detectors
G64GM™ monitor: intended for use with existing GM probes
GIM 204K - Very Wide Range Gamma Area Monitor
Monitors dose rate in nuclear facilities for personnel exposure or for process monitoring.
FEATURES
Wide measurement range
Compact and reliable
Available with or without display and local signaling
1E qualification and embedded safety related software
Available under 10 CFR 50 App.B, ASME NQA-1 and IEC61226 programs for safety related applications
DESCRIPTION
The GIM 204K monitor forms part of the RAMSYS™ product line. It has been developed to monitor dose rate or equivalent dose rate in nuclear facilities for personnel exposure as well as for process monitoring.
This monitor is available in many versions: with or without display, integral or remote detector, dose rate or equivalent dose rate, fixed or portable, etc.
GIM 201K Low Range Gamma Area Monitor
Gamma area monitor ion chamber based for accelerators
The GIM 201K monitor is a low range gamma area monitor developed to monitor absorbed equivalent dose rate in nuclear facilities or laboratories for personnel exposure.
FEATURES
Wide measurement range
High detector TID
Up to 150 meters (492 ft) between detector and processing unit
Available with or without display and local signaling
Suitable for continuous and pulsed radiation fields
Compact and reliable
DESCRIPTION
The GIM 201K monitor forms part of the RAMSYS™ product line.
It has been developed to monitor absorbed dose rate in nuclear facilities for personnel exposure. Its design makes it especially suited for operation in accelerators. Ionisation chamber made of high-density polyethylene allows the measure of short duration pulsed radiation fields when halogenated and/or material activation is an issue.
IM 201M Mobile Iodine Monitor
Iodine Monitoring
Continuously measuring the gamma volumetric activity of radioactive iodine sample contained in air drawn from stacks, ventilation ducts or working areas.
FEATURES
Embedded 241Am source for energy spectrum stabilization against temperature changes and aging
1024 channels spectrum analysis
Effluent trapping of both molecular and organic forms of iodine
Can be used as temporary bypass for IM 201S™ or IM 201L™ monitors to maintain full monitoring capability during maintenance
DESCRIPTION
The IM 201M monitor forms part of the RAMSYS™ product line.
It has been developed to continuously measure the gamma volumetric activity of radioactive iodine sample, in both molecular and organic forms (methyl iodine), contained in air drawn from stacks, ventilation ducts or working areas. An NaI scintillation detector faces the activated charcoal cartridge in which radioactive iodine is trapped. The proximity of the detector and the cartridge, enclose within a 4 π/5 cm (4 π/2 in) lead shielding, serves to optimize detection efficiency.
A radioactive 241Am source built into the NaI chrystal allows compensation of temperature and aging related drifts. The spectrometry capability, based on a 1024 channel spectrum analysis, allows radio iodine isotope localization.
NGM 209M Mobile Low Range Noble Gas Monitor
The NGM 209M monitor samples air in discharge stacks or ventilation ducts.
FEATURES
Dynamic gamma radiation compensation with shielded gas detection sensor
Absorbed gamma dose rate indication
Operate as a stand-alone monitor and/or can be integrated in a RAMSYS™ network using a wireless network (radiomodem) or a RS485 serial link
DESCRIPTION
The NGM 209M monitor from the RAMSYS product line has been developed to sample air in discharge stacks or ventilation ducts.
The dual silicon diode detector integrated in a 4 π/3 cm (4 π/1.18 in) lead shielded sample volume guarantees high reliability of the measurements.
The first silicon diode detects the beta/gamma radiation from sample volume and the gamma ambient radiation (background). The second one detects gamma radiation from the sample volume and the gamma ambient radiation.
This allows noble gas beta measurement with dynamic gamma compensation by the processing algorithms.
NIM 201K Neutron Irradiation Dose Rate Monitor
FEATURES
Detector for indoor and outdoor applications
H*(10) measurement
Available with or without display and local signaling
Wide and high neutron energy range (2.5 10-8 to 16 MeV)
Compact and reliable
DESCRIPTION
The NIM 201K monitor forms part of the RAMSYS product line. It has been developed to monitor in real time the ambient dose equivalent rate. It provides operational dose rate in units of H*(10) derived from neutron fluence according to ICRU 57 recommendations. The helium-3 proportional counter (cylindrical tube) placed inside a polyethylene sphere facilitates detection of thermal and fast neutrons. Its large energy range, associated with modular design makes it efficient, reliable and very sensitive. It is used effectively in nuclear reactors, subcritical stacks, neutron generators and irradiators, and in accelerator facilities.
