### (a) Radiographic Inspection (RT)
**1. Principle**
Radiographic Testing is a non-destructive testing (NDT) method that uses penetrating short-wavelength electromagnetic radiation (X-rays or Gamma rays) to examine the internal structure of materials. The fundamental principle is based on **differential absorption of radiation**.
* A beam of radiation is directed at the test object.
