DESCRIPTION

AirTrack-Mobile is a compact version of aerosol monitors in terms of advanced design solutions for automatic alpha/beta spectrometric measurements.

A special version of the Silicon Ion Implanted Detector with area 600 mm2 is used for alpha and beta spectrometry. The metalized coating of entrance window with thickness of less than 2 mm provides mechanical and chemical protection of the detector. Measurements can be carried out in high background conditions – compensation of radon, thoron and their progenies is performed algorithmically by spectrometric measurements. To reduce the influence of gamma background an auxiliary SIID is used to measure beta equivalent pulses and subtract them from the total beta counts.

A modular approach to the design of AirTrack-Mobile hardware and software enables fast troubleshooting of system issues. Moreover, modular designs allow easiness of upgrades and/or integration of future equipment. In general, the system and its components are ergonomically designed to ensure ease and comfort of operation.
