Abstract:	摘要： Regularity visual inspections are performed on steel wire ropes of suspension bridges. However, because the steel wire ropes were coated with plastic materials, inspectors could not visually detect the deterioration conditions of the ropes. In this paper, radiation tests and electromagnetic testing were compared. The gamma rays used in the radiation tests were employed to develop two assessment techniques, namely the exposure time formula and sensitivity assessment of steel wire ropes. Actual tests showed that such techniques can be adopted to evaluate the defects of steel wire ropes and help engineers improve the safety of suspension bridges. •This paper detected the defects of the wire rope successfully using gamma rays.•The defects of wire rope can be presented by the images.•The size of the defect can be identified in the inspection photograph. 出版者： Elsevier Ltd 出版日期： 2015-10-01 出處： NDT & E international : independent nondestructive testing and evaluation, 2015-10, Vol.75, p.80-86 版權： 2015 Elsevier Ltd 識別號： ISSN: 0963-8695 識別號： EISSN: 1879-1174 識別號： DOI: 10.1016/j.ndteint.2015.06.006
