Description

The Cartogam real-time portable gamma-ray imaging system is specially designed for in situ gamma measurements to locate radioactivity at nuclear sites. It can be used to provide radiation intensity maps of areas during normal operations, to evaluate radiological source location when planning for maintenance or decommissioning operations and to quickly evaluate source positions during incidents, accidents, or emergencies.

The high level of portability and the possibility of remote operation of Cartogam lead to a significant reduction of human exposure complying with the ALARA principle.

Cartogam is easy to carry, easy to use, and can be easily decontaminated, therefore making it practical for use in contaminated areas during equipment maintenance activities.

Cartogam is the perfect tool for real-time mapping of gamma emitting sources - it allows fast localization of radionuclides within contaminated areas.

The Cartogam system is composed of a small detection head and a portable PC. Acquisition, image analysis and data storage are managed through the GammaView software.

The detection head has been specially designed for taking into account the harshest environmental constraints of operations within hot areas of nuclear sites.

The Cartogam head is splashproof, fully decontaminable and is both light weight and portable, making it perfectly suited for an extended range of applications.

The user-friendly operation of Cartogam drastically reduces the exposure time of operators in accordance with the ALARA principle - the detection head can be remotely adjusted via a Pan and Tilt or specific remote manipulator devices. The PC to detection head distance can be up to 200 m (600 ft).

The Cartogam operation is very simple - full control is made from the GammaView software. Control of acquisition, analysis of scenes and data storage are particularly user-friendly and use a standard Windows® "Look and Feel" man-machine interface.

After selection of the area to be mapped and the acquisition mode (low or high counting rate), the operator starts the automatic sequence of acquisitions.

At the end of the exposure time, Cartogam generates a composite image of the gamma map, superimposed on the visible image. The gamma image intensity is automatically normalized to full scale.

The hot spots may also be evaluated in dose rate according to a user-defined nuclide or energy.

The acquired raw data (composed of visible and gamma images, and other various parameters) is stored to ensure data integrity. Enhanced storage functions are available (key words associated to acquired images, etc.).
