Title: Magnetic susceptibility in environmental applications: comparison of field probes
Abstract: Magnetic susceptibility is a convenient measure of determining the concentration of (ferri)magnetic minerals by rapid and non-destructive means. The present paper aims at defining the characteristics of three field probes, commonly used to measure magnetic susceptibility: the Bartington MS2D and MS2F probes, and the Geofyzika KT-5 Kappameter. Two other instruments, the Bartington MS2B probe and Geofyzika KLY-2 Kappabridge are used for calibration. The results show that "true" magnetic values are either over- (196%) or underestimated (42%) in comparison with MS2D probe when the MS2F probe is buried in or placed on the surface of cement samples. The KT-5 Kappameter gives true values of susceptibility (102%) as referred to the KLY-2 Kappabridge, and the MS2D probe reads 90% of true values based on the MS2B probe. Depth penetration of each sensor is only a few centimeters. At a depth of 6 cm, the MS2D probe integrates 90% of the susceptibility signal. The KT-5 Kappameter records about 90% in the first 2 cm. For the MS2F probe, almost all of the signal is located within 1 cm around the sensor.
