A continuous increase has been observed in the number of diagnostic X-ray machines in the Republic of Korea, from 89,955 in 2019 to 97,745 in 2021. Classification based on the types of X-ray equipment showed that the portion of general equipment with an integrated tube-high voltage (HV) generator used in radiography or fluoroscopy accounted for the largest proportion (26%, 25,000), followed by general equipment with separate tube-HV generator (22%; 21,237), intra-oral equipment (14%; 14,136), equipment for panoramic imaging (7%; 7,332), dental computed tomography (CT) (15%; 14,663), equipment for bone mineral densitometry (9%; 9,154), mammography equipment (4%; 3,702), and whole body CT equipment (3%; 2,521). The district-based categorization revealed that Seoul had the largest number of diagnostic X-ray machines (22.9%; 22,362), while Sejong had the smallest number (0.6%; 544). Based on the period of use, 35.4% (34,643) of total equipment had been used for 5 years or less. As the number of diagnostic X-ray equipment increases, the importance of safety management in medical radiation will also increase and more efforts will be required to ensure radiation safety.
