- The Nuc Scout monitors the local dose rate as well as the activity of up to 28 user selectable nuclides. The results are available as time distribution over the whole sampling period. The sampling interval can be adjusted by the user. A complete energy spectrum is saved for each interval on the internal memory card.
- The unit is equipped with an integrated GPS receiver which allows the local assignment of the acquired data.
- The Nuc Scout can be calibrated by the user, so by the way it is possible to determine the detector efficiency for any sampling geometry which can be used later on.
- The Nuc Scout offers two different algorithms for the activity calculation of the several nuclides. The user may decide between the powerful PSV (peak shape verification) algorithm and the well-known trapezoid method (e.g. for calibration purposes).
