Introduction to Non-destructive Testing

Introduction to Non-destructive Testing The use of noninvasive techniques to determine the integrity of a material, component or structure or quantitatively measure some characteristic of an object. Inspect or measure without doing harm. Definition of NDT Methods of NDT Visual What are Some Uses of NDE Methods? Flaw Detection and Evaluation Leak Detection Location Determination Dimensional Measurements Structure and Microstructure Characterization Estimation of Mechanical and Physical Properties Stress (Strain) and Dynamic Response Measurements Material Sorting and Chemical Composition Determination Fluorescent penetrant indication When are NDE Methods Used?

The radiation used in radiography testing is a higher energy (shorter wavelength) version of the electromagnetic waves that we see as visible light. The radiation can come from an X-ray generator or a radioactive source. High Electrical Potential Electrons + - X-ray Generator or Radioactive Source Creates Radiation Exposure Recording Device ...

Aug 11, 2009 · NASA has been aware of the risk of radiation exposure from its outset, based on studies leading from observations of atmospheric high-nuclear-charge (high Z) cosmic rays first reported in 1948 (Wilson et al, 1991, and references therein) and on direct measurements of the space radiation starting with Van Allen
