Radiometrische Feuchtemessung mittels Gamma-Strahlung
Abstract
For determining the density of wood and bricks, the attenuation of Gamma-radiation by the material can be measured. Based on this idea new equipment for stationary and mobile use has been developed. In this case 241AM with the energy of 60keV serves as a Gamma-ray source. From differences of time-spaced measurements the moisture distribution and changes in moisture can be calculated. Therefore shrinking and swelling of the material should be taken into account.
