For examination of underground water flow fluorescent substances are used since a long time, so called Tracer. These will be added to the water in appropriate dosage, and gives it the particular Tracer typic colour. Since almost one hundred years uranin is used for this purpose. The pure uranin powder or highly concentrated solvent has a dark red colour in the water. They don’t fluoresce. Only at greater dilution the Uranin colours the water in dependence of the dilution fluorescent light green to green. Under UV light (365nm) the effect is more visible.

Uranin shows no sign to attach on rock surfaces and therefor it is suitable to detect the underground water flow of water. The adhesion poperties on many, non absorbent building materials ar also not particularly pronounced. Because Uranin decomposes under daylight within a few days, among other things it can be used for leak detection, for example leaking house walls. This characteristic makes it only limited suitable for examination and marking of surface water, except the effect is required concretely.
Uranin is only a marking agent and it is not suited for food colouring.
