ABSTRACT Apparatus and methods for producing a signal or signals related to the moisture content of a substance using impedance, radio frequency loss or dielectric loss techniques are disclosed. Apparatus and methods for producing a signal or signals related to the density and/or thickness of a substance using backscattered gamma-rays are described. Apparatus and methods using a combination of a.c. impedance, radio frequency or dielectric loss and backscattered gamma-ray techniques for producing signals related to the moisture content, density and/or thickness of a substance are also described. Means and methods for determining the moisture content, density and/or thickness of the substance from the signal or signals are disclosed. The apparatus and methods are particularly applicable to determining the moisture content, density and/or thickness of coal and coke.
