Study Notes
Penetrating Radiation
- Penetrating radiation is a type of radiation that can pass through solid objects.
- X-rays are a type of penetrating radiation.
History of X-ray Radiography
- Wilhelm Conrad Röntgen discovered X-rays in 1895.
- In 1896, X-rays were first used by physicians to identify bullets in wounded soldiers.
- In 1912, X-rays were first used to inspect metal parts.
- The beginning of industrial radiography was in 1913.
- In 1931, 1000 kV X-ray generators were developed by General Electric (GE).
History of Radioactivity
- Henri Becquerel discovered natural radioactivity in 1896.
- In 1898, Marie Curie discovered Polonium and Radium.
Gamma Radiography
- Industrial gamma radiography uses Cobalt 60 and Iridium as radiation sources.
- Gamma rays are a type of electromagnetic radiation with very short wavelengths (1/10 nm).
- Gamma rays are similar to X-rays.
Introduction to Radiographic Testing (RT)
- Radiography is used in various fields such as medicine, engineering, forensics, and security.
- In Non-Destructive Testing (NDT), radiography is the most important and widely used method.
- Radiography has several advantages over other NDT methods.
- One of the major disadvantages of radiography is the health risk associated with radiation exposure.
- Radiographic Testing (RT) is a method used to inspect materials for hidden flaws.
