Abstract:Image quality indicator (IQI) is selected based on the single and/or double wall thickness of pipe with or without considering the radiographic techniques or applied radiation source (x ray or gamma ray), in accordance with the sensitivity requirements of reference codes. Discrepancies in the codes and standards for sensitivity evaluation and IQI selection have been investigated in the present work and some experiments have been performed to measure the gamma ray or x-ray radiographic sensitivity for pipes and… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
