The EASYSCAN mobile station is a robust and handy system designed to perform an easy, fast and reliable spectrometric analysis of radioactive material contained in drums, where the fine spectroscopy provided by HPGe-based systems is not needed.
The EASYSCAN main components are:
The detectors are distributed in a vertical array of 4 units. Each detector is provided with a 20 mm lead shielding around the active volume (end-cap), acting at the same time as a collimator: each detector analyses a specific subsection of the drum, allowing identification of inhomogeneities and hot-spots. The system can achieve an MDA of 0.05 Bq/g (15 minutes measurement, 0.2 g/cc density, 220 l drum).
The wheel-mounted mechanical support structure is robust and very easy to move around, so EASYSCAN can be easily deployed in different locations without having to disassemble the scintillators or the electronics. Thanks to the anti-vibration absorbers, it can also well resist accidental bumps that may normally occur during its re-location.
Radioactive drums of different volumes can be characterized with EASYSCAN, i.e. 220, 300, 400 liters and even bigger ones.
The operator can quickly set each detector at the desired position (height) thanks to four independent manual wheels, located on the top of the structure.
The EASYSCAN user interface consists in a sophisticated yet easy-to-use software. The one-button scan procedure is designed to be extremely essential: the operator needs only to set the measurement time and then simply start the acquisition.
A 15-minute measurement time is enough for most cases where low to very-low radioactive concentrations shall be measured. Measurement reports are provided at the end of each scan.
EASYSCAN comes with a full MONTE CARLO characterisation of each scintillator response function. Both the response functions and the measurement report can be customized according to specific requirements in terms of isotopes to be searched, material density, drum volume, etc.
