    Radiographic Testing(RT)

    Radiographic Testing

    Industrial radiography involves exposing a test object to penetrating radiation so that the radiation passes through the object being inspected and a recording medium placed against the opposite side of that object. For thinner or less dense materials such as aluminum, electrically generated x-radiation (X-rays) are commonly used, and for thicker or denser materials, gamma radiation is generally used.

    The RT Level I course topics include:

    • The principles and theory of performing radiographic testing, including a perspective on radiographic materials, industrial radiography, and protection

    • A math review

    • Fundamental properties of matter

    • Radioactive materials

    • Types of radiation

    • The interaction of radiation with matter

    • Biological effects of radiation

    • Radiation detection

    • Exposure devices and radiation sources

      Also includes basic principles of radiography; formation and characteristics of radiographs and radiographic film; image quality; film handling and processing techniques; radiographic exposure techniques and fluoroscopic techniques.

    The RT Level II course topics include:

    • The principles and theory of performing radiographic testing, including a review of basic radiographic principles

    • Operation of darkroom facilities, techniques and processing

    • Indications, discontinuities and defects

    • Manufacturing processes and associated discontinuities

    • Review of radiological safety principles

      Also includes fundamentals of radiographic viewing; application techniques; evaluation of castings and weldments; and standards, codes, procedures and reporting
