Spectral Gamma Sonde

Product Information

The spectral gamma version can operate in both spectral and in 5 window mode. The
GM version uses a set of two Geiger-Muller detectors to cater for the high count rates in
uranium ore. The shielded version allows the user to filter out low energy gamma rays
in high grade uranium. This allows for a more linear operation in high gamma counts
environments. The sonde also provides for automatic dead time measurement and
