Radiometric density measurement for silage compaction in bunker silos CIGR Journal
Hoffmann, Thomas; Geyer, Sabine; Bittner, Jürgen; Kögler, Robert; Schima, Mirko.
Certain minimum densities should be targeted when storing silage in bunker silos.  However, farmers lack facilities to measure the actual density and then steer the compaction passes.  This study was aimed at developing a measuring device for onsite density measurement.  The basis of the measuring device was a source of caesium radiation with an activity of    37 MBq and a sodium iodide scintillation detector.  The measuring device used the backscattering method.  The source and detector were located in a measuring wheel that was connected with the tractor via the rear three-point linkage.  During measuring passes on bunker silos both the density increase in the case of several crossings and the elastic recovery of the material could be seen clearly.  In...
