DESCRIPTION

AirTrack-i is the State of the Art among Iodine Monitors, in terms of advanced design solutions and performances of the Gamma spectrometric measurement chain and cartridges changer mechanics.

It has the same functional and mechanical construction of the AirTrack-Sr Aerosols Monitor; both equipment utilize the same gamma digital MCA.

In this application, thanks to the superior characteristics of its detector, the MCA is set-up for 4k channels, twice the number of channels normally usable with less performing scintillation detectors, same as for AirTrack-Sr.

The innovative unique use of a SrI2(Eu) crystal with its very low intrinsic background and very high photonic yield makes possible at a reasonable cost the implementation of an industrial grade equipment with laboratory grade performances on-line.
