Abstract
A method for measuring counting rates or measured variables dependent on the counting rates for determining a density profile of at least two substances with different densities arranged within a container by using a plurality of detectors is provided. The method includes recording respective gamma rays which have penetrated at least partially through at least one of the substances by using the detectors, and generating a respective counting rate or a respective measured variable dependent on the counting rate only on the basis of respectively recorded gamma rays of which the respective gamma energy is greater than or equal to an energy threshold value, the energy threshold value being a minimum of 0.5 times a Compton energy value of a Compton gap of the gamma rays.
