Abstract:
Gamma-ray imaging of reinforced concrete is discussed. It is shown that the technology can be used with minimal risk of radiation exposure and can provide extensive data regarding conditions within concrete structures. An additional example of gamma-ray application for inspection of post-tensioned girders is included with the online version of this article.
