Exploranium GR-135 Plus Identifier Radioactive Isotope Identification Device (RIID)

The handheld GR-135 Plus Identifier Radioactive Isotope Identification Device is an advanced version of its well-known predecessor, the GR-135. It is outfitted to detect the presence of radioactive emissions in field operations where ease of use and simplicity are critically important. The GR-135 Plus is a gamma-ray spectrometer that performs three functions in one handheld instrument. The instrument allows the user to Survey (locate radioactive source), measure Dose (determine the exposure hazard level) and Analyse (identify) nuclides for risk assessment. The GR-135 Plus features new advanced, high-performance nuclide identification software, new high-sensitivity Neutron detector and simplified user interface screens.

Applications

Government, first responder organisations and private businesses around the world can count on the leading edge technology of the GR-135 Plus to detect and intercept nuclear materials and radioactive sources. This isotope identification device is used by:

• Customs and security
• Emergency response teams
• Nuclear facilities
• Police
• Firefighters
• HAZMAT response teams
• Waste management
• Medical facilities

Features

The GR-135 Plus is as easy to use as Grab, Point and Click. With dual mode automatic or manual operation, the GR-135 Plus is controlled using a one button, thumb operated multi-function joystick switch. The GR-135 Plus is well balanced and easily carried and operated with one hand. Its multiple on-board detectors enhance the capability of isotope identification such as identifying emissions from nuclides such as HEU (Highly Enriched Uranium) and Pu (Plutonium).

Other key features in this isotope identification device include:

• 4 pre-defined nuclide libraries
• Neutron detection
• Optional docking station for immediate readiness and data download to a PC
• Displays operator instructions, procedures and warnings
• ‘Eyes-free’ audio warning system with earphone and volume control
• Multi-language capability

Benefits

The GR-135 Plus is to be used for the quick and accurate detection and identification of radioisotopes. With proper training, even the most inexperienced user can search, measure and identify nuclides for risk assessment. Whether it is climbing a ladder, navigating though dense smoke, inspecting containers or vehicles for concealed nuclear material, GR-135 Plus’ single button operation provides accurate, quick and efficient identification.

Georadis RS-111 Compact Hand Held Radiation Detector

The RS-111 HANDY SCINT is a compact hand held radiation detector specifically designed to quickly determine the location of radioactive material. The high sensitivity RS-111 is an ideal instrument for surveying people, packages or materials, quickly and simply detecting Gamma Ray emitting radioactive sources in various combinations and in most situations.

The small size and light weight of the RS-111 together with the balanced handle, equipped with a single thumb button, allows easy one handed operation. The single ON/OFF button also allows easy set up of a limited number of working parameters.

The RS -111 features a large numeric LCD display showing, user selectable, either actual counts per second (cps) or dose rate (based on equivalence to Cs 137). The visual display is complimented by a loud variable pitch audio tone, proportional to the intensity of the gamma radiation detected, for eyes free searching. The threshold for audio indication is adjustable manually or automatically and reflects the current background. The audio indication can be switched off if required.

For working in potentially dangerous situations, a maximum allowed dose rate or cps rate can be set. If the dose rate or cps rises above this level it triggers an automatic acoustic alarm warning.

Typical Use

• Nuclear facilities
• Scrap metal recycling plants
• Recycling facilities
• Waste management
• Production facilities
• Geophysical applications
• Security and surveillance operations
• Hospitals and special laboratories
• Recycling facilities

The RS-111 HANDY SCINT has a dustproof, shower proof, lightweight aluminium case. A detachable plastic boot with carrying strap provides additional protection for difficult situations.

The unit is powered by four AA type batteries. A fully automatic charger is integrated in the unit for use with rechargeable (NiCd or NiMH) batteries. Nonrechargeable batteries (Alkaline) can also be used if necessary (but not recharged). The RS-111 is supplied in an aluminium carrying case.
