Radiography uses differential absorption of radiation penetrating a test object coupled with recording of an image on film to detect features of the test object that exhibit a difference in thickness or physical density as compared to the surrounding material. The rule of thumb with radiography is that features that exhibit a 1% or more difference in absorption compared to the surrounding material can be detected.
