Abstract

Jnvestigatione on sensibility definition and efficieneg of the testing were fulfiled with high current betatrons at 15-50 MeV energy of radiation.Radiation energy, thickness of the steel, focus distance, Kinds of Roentgen emulsion and screens were variated. Technical parameters of two betatrons and their NDT posibilities are in the tabl. 1.
