In the Radiographic Testing (RT) Level I course, the student will learn the theory and principles of radiation and how they apply to the basics of radiography. There are many variables to be controlled in order to produce a high quality image. RT is one of the major volumetric methods with Ultrasonic Testing being the other. Subjects also include the development of RT techniques for a wide range of applications, handling and processing radiographic film, and the safe use of RT equipment.
