Defects appear. Each pulse is repeated after echo. What are the two major types of rays used in radiographic inspection. Explain each type. Gamma rays-electromagnetic radiation of high frequency waves emitted by the nucleus of an atom during nuclear reaction. X-radiation-created from rapidly moving negatively charged particles called electrons Name any 4 methods of NDT discussed in this section and give on limitation of each and one advantage of each. Ultrasonic-rough surfaces interfere, not limited to metal Eddy current-time consuming, portable Magnetic particle-ferro magnetic only, very sensitive Liquid penetrant-permanent results not available, low cost What is the formal definition of NDT?
