Abstract

|
|
|
Since X-ray has been discovered by W. C. Roentgen in 1895, it has been used as an essential means to diagnose diseases. In Korea, the number of diagnostic X-ray equipment has continuously increased from 75,369 in 2013 to 78,347 in 2015. Categorized by districts, the largest number of diagnostic X-ray equipment was 18,352 (23.4%) in Seoul, while the smallest was 199 (0.3%) in Sejong. According to types of X-ray equipment, 25.0% (19,592) of the total number (78,347) was shown as a general equipment with tube-HV (high voltage) generator-separated, 18.3% (14,360) as general equipment with tube-HV generator- integrated, 7.6% (5,927) as equipment for bone mineral densitometry (BMD), 19.1% (15,003) as intra-oral equipment, 15.9% (12,483) as equipment for panoramic imaging, 7.3% (5,744) as dental CT, 2.9% (2,238) as whole body CT, and 3.8% (3,000) as equipment for mammography. In terms of age of diagnostic X-ray equipment, most of the X-ray equipment, 31.8% (24,946), was “equal or less than 5 years”, while the “unknown” age group accounted for 6.4% (4,987) of the total number of equipment. As the number of diagnostic X-ray equipment increases, the importance of safety management in medical radiation also increases. More efforts would be required in order to prepare the environment for “safely using radiation”.
