Application of radioactive isotopes in the field of investigations of the means of transportation wear

The Station for governing of isotope technique ensures application of radioactive isotopes in the transport of the GDR. The main directions of the isotope application are investigations of wear and leaks. It is reported about the wear investigations performed on models and real structural elements at laboratory testing stands as well as on the real structural elements in the exploitation conditions. Special attention should be paid to the numerous measurements of wear of engines, rails and so on. Data and valuable results have been obtained about the problem of the short-term wear measurement. Measurements of leaks by means of radioactive isotopes application is used for investigations of the hermeticy of the refrigerator tronsport means, heating systems and clymatizing installations of the carriges as well as stationary installations. Then, measurements have been done of leaks in pipelines as well as determinations of their lacalization and intensity. General and specific advantages of separate methods are discussed
