We investigated the causes and trends of incidents related to radiography. From April 2014 to March 2016, 384 incident reports related to radiography were posted. We analyzed based on the nature of the incidents and the experience period of radiological technologist (RT). The types of incidents were ‘Incorrect examination order by medical doctor’ (50.0%), ‘X-ray retake’ (24%), ‘Incorrect examination procedure’ (9.9%), ‘Fall or injury of the patient under examination’ (3.6%), ‘selection error of X-ray detector’ (3.1%), ‘patient mismatch’ (1.8%), ‘overdose’ (1.3%), and ‘others’ (a malfunctioning device, trouble of systems and the other) (6.5%). There was no relationship between the number of incidents per person and the experience period as RT; (7.8/person for <3 years of experience, 9.7/person for 3–10 years, 6.4/person for 11–25 years of experience, 7.4/person for <25 years of experience). The experience period as RT are related to some types of incident reduction. ‘Fall or injury of the patient under examination’ and ‘overdose’ were more frequently reported by RTs of shorter experience (<3 years and 3–10 years of experience) than RTs of longer experience (11–25 years and <25 of experience). On the other hand, ‘patient mismatch’ and ‘selection error of X-ray detector’ were more frequently reported by RTs of long experience than RTs of short experience.
