Radiography & Digital Radiography
Training Course
Because of the penetration and absorption
capabilities of x and gamma radiation, radiography is used to
test a variety of products such as welds, castings, forgings and
fabrications.
Radiographic Testing (RT)is one of the primary
non-destructive test methods in use today.
Radiographic
Testing usually requires exposing film to x or gamma rays that have
penetrated a specimen, processing the exposed film and interpreting the
resultant radiograph.
Advantages:
1. Can be used with most materials.
2. Provides a permanent visual image.
3. Reveals the internal nature of the material.
4. Discloses fabrication errors.
5. Reveals structural discontinuities.
Limitations of RT:
1. Impractical to use on specimens of complex geometry.
2. The specimen must lend itself to two-side accessibility.
3. Laminar type discontinuities are often undetected by RT.
4. Safety considerations imposed by x and gamma rays must be considered.
5. It is relatively expensive means of non-destructive testing.
Safety Considerations
Because radiation cannot be detected by any of our five senses, strict
compliance with safety regulations is required. Radiation can cause
damage to, or destruction of, the calls of living tissue. It is
essential that radiographic test personnel be continually aware of the
radiation hazard and cognizant of safety regulations.
