What exactly is neutron radiography for imaging of a water tower, and what kind of data does it provide?

Hello, Neutron radiography is a non-destructive process that allows for identification of the presence of water in solid materials. It has a high penetration depth, up to a thickness of 30 cm in the case of an exterior wall. Without knowing the specs of your installation, I think that the technique might well enable you to locate a leak in the water tower that is not visible from the outside, thereby pinpointing areas that aren’t watertight.
The neutron probe measures the moisture content of solid components. The device generates a neutron beam that can pass through solid material, even metal, but is slowed down in water. Measurement of the attenuation rate of the neutrons provides very precise readings about the condition of the component being inspected. The operator performs grid calculations, and the readings are then transferred to create a color digital map.
