Nuclear Gauging System
4. Moisture gauge:
▪ Used to measure moisture content of bulk materials e.g. soil, sand,
concrete, lime and coke.
▪ It works on transmission or backscattering principle using a neutron
source or both neutron and gamma source.
▪ It works based on thermalization of fast neutrons by water molecules
contained in the material.
▪ Higher water content (higher moisture content) will thermalize more
neutrons.
