AirTrack-I is the state-of-the-art among Iodine monitors in terms of advanced design solutions for automatic gamma spectrometric measurements and cartridges changer mechanics.
The innovative unique use of a SrI2(Eu) scintillation crystal with high energy resolution and low intrinsic background ensures maximum reliability in the identification of radioactive iodine and reduces the detection limit of its concentration.
It shares the same functional and mechanical design of the AirTrack-Sr Aerosols Monitoring station. Both monitors are constructed on a modular principle and have interchangeable parts, but AirTrack-I uses special charcoal filters. This charcoal material is selective, it will not trap other gases, and therefore the sample will be enriched with only I-131. When it is impregnated with some chemicals, the activated charcoal can effectively adsorb both organic and elemental iodine.
