How radioisotopes are used in noninvasive detection of defects in pipes?

Radioisotopes are utilized in noninvasive detection of defects in pipes through a technique called radiography. In this method, a radioisotope emits gamma rays that penetrate the pipe material, with the intensity of the radiation being affected by the presence of defects such as corrosion or cracks. By capturing the transmitted radiation on a detector or film, technicians can create detailed images that reveal internal flaws without the need for invasive procedures. This approach provides a safe, efficient, and effective means of assessing the integrity of piping systems.
