QuantAir
the measuring andquantification of
airborne emissions

QuantAir
QuantAir is a unique solution for in-field air
monitoring that provides high performanceand detection capabilities with accurate infield quantification.
The lightweight system incorporates an optimised lead/copper shield enabling operation in both standard andraised backgrounds. This enables monitoring of potential
activity build up and acts as a live warning system,
allowing remedial actions to be carried out at the timeof release. This minimises potential intake and increase
worker safety.
Initially setup to measure 131I levels, QuantAir can be
tailored to any radionuclide. It works with most current
air sampling devices, including L60, L100 and Hi-Q airsamplers measuring carbon cartridge Maypack filterswith the potential of other configurations.

Features:nMeasures 131I levels

nWorks with existing air
sampling devices including
L60, L100 and Hi-Q airsamplersnLight weight systemn

Audio visual alarm with mutecapabilitynUser defined activity alarm
thresholdnAdjustable confidence levels

QuantAir incorporates the Kromek GR1, the world’s
smallest high-resolution room temperature gamma rayspectrometer utilizing a cadmium zinc telluride (CZT)
detector and offering world-leading specification in acompact form. With an energy resolution of less than
2.5%, the GR1 provides clear separation of gamma
energy peaks.

Applications:nEnvironmental monitoringnDecommissioning
Kromek’s GR1 spectrometerCalibration is pre-set during manufacture using calibration
sources and simulated efficiency factors. The software
also offers a user efficiency calibration to use with
Maypacks of known 131I activity.
Activity analysis algorithms offer accumulated activity
output as well as an instantaneous activity output. During
a measurement, sophisticated algorithms continuallycompare the calculated activities with the activity alarmthreshold, which will alarm if above this threshold. The
user can define the activity alarm threshold.

Dynamic search and alarm capability.
Dynamic search alarms utilise statistical significancealgorithms that can be configured to the user’s needs. It
includes an audio visual alarm with mute capability andadjustable confidence levels, as well as screen locking
capabilities when measuring.
Results of the algorithm outputs are stored in separate
CSV files that can be exported via USB.
