What does RT stand for in NDT terminology?

In non-destructive testing (NDT) terminology, RT stands for Radiographic Testing. This method utilizes ionizing radiation to examine the internal structure of a material, typically to identify defects like cracks, voids, or inclusions that may not be visible through other testing methods. By using X-rays or gamma rays, RT can generate images on film or digital detectors, providing a detailed visualization of the tested object and allowing for thorough inspection without damaging the material.

The importance of RT lies in its ability to assess the integrity of critical components in structures like pipelines, welds, and aerospace parts, ensuring safety and reliability. This technique is widely used across various industries, including construction, manufacturing, and aerospace, highlighting its significance in quality control and compliance with safety standards.
