ABSTRACT:
The teachings provided herein are generally directed to a non-destructive method of measuring a moisture content profile across a dimension of a hygroexpansive, composite material using radiation and a volumetric shrinkage correction. The measurement of a series of moisture content profiles over time can provide, for example, a measure of the movement of moisture during the process of drying of the composite material.
