CARTOGAM - a portable gamma camera for remote localisation of radioactive sources in nuclear facilities
Abstract
We have developed a compact gamma-imaging system, CARTOGAM, for remote localisation of radioactive sources in nuclear facilities. This system is under industrial development and commercialisation by the firm EURISYS Mesures. The most specific characteristics of CARTOGAM lie in its size (8 cm in diameter) and mass (15 kg for the detection head, including the shield), which make it portable by a person. As an example, CARTOGAM detects a 660 keV source producing a 0.4 μGy/h dose rate at the camera location in 10 min. The angular resolution at that energy ranges from 1° to 3°, depending on the field of view (30° or 50°) and scintillator thickness (2 or 4 mm). We present here a review of the specifications of the camera and show a few images illustrating its performance.
