What is MAUD (Digital AUtoradiography Measurement) ?
MAUD (Digital AUtoradiography Measurement) is a cutting-edge camera for in situ alpha & beta radiation detection, difficult to measure. The objective is to assess the potential alpha and beta contamination (in Bq/cm2) of a surface in a facility to be dismantled.
The portable camera is placed in direct contact with a raw surface to investigate. After an acquisition of few minutes the device provides the level of contamination and the image of the emerging radioactivity coming from the surface. The measurement of a large surface can be automatized.
MAUD is based on solid scintillators which emit light when expose to radiations. The light is collected using 64 Silicon Photo Multipliers, a new type of photosensors, with high gain, large photodetection efficiency and low voltage bias. Analogic signal is processed using dedicated electronic.
The technology is original in terms of detection technique (SiPM), efficiency, robustness and software. MAUD represents a cost-effective gain in characterization without time consuming destructive analysis.
