Application of RNB for high sensitive wear diagnostics in medicine technique and industry Original Research Article

The RTM—Radionuclide Technique in Mechanical engineering—is now extended to the solution of world wide problems in medicine technique (prosthetics), and in development of modern materials (synthetic materials, ceramics, hard coatings, etc.) and their industrial application. RNB—Radioactive Nuclear Beams of 7Be or 22Na—may enable the required extreme thin radioactive surface labeling (several micrometers) of synthetic materials for wear measurements without producing radiation damages of influence to the wear properties of the material. The function principle and special properties of the RTM on-line wear diagnostics and its components, the measurement methods, the radioactive surface labeling, and the measurement instruments are explained. The quality features of a 7Be and 22Na-beam for RTM application are specified.
