질병관리청이 발간한 ’2025년 국민 의료방사선 평가 연보’에 따르면, 지난해 국민의 의료방사선 검사 건수는 총 4억 3159만 건으로 국민 1인당 8.4건이었습니다. 이는 전년보다 4.6% 늘어난 수준입니다. 검사 건수는 2021년 3억 3313만 건(1인당 6.4건)에서 2025년 4억 3159만 건으로 약 29.6% 증가했고, 같은 기간 피폭선량도 1인당 2.64맨·시버트에서 3.24맨·시버트로 약 22.6% 늘었습니다. 종류별로는 일반 X선 촬영이 3억 2960만 건으로 전체 검사의 76.4%를 차지해 가장 많았습니다. 반면 CT는 1633만 건으로 검사 건수의 3.8%에 불과하지만, 전체 피폭선량의 67.1%를 차지했습니다. 질병관리청은 의료 기술의 발전과 고령화, 건강검진 활성화 등으로 의료방사선 검사의 활용도가 계속 확대되고 있다고 설명했습니다.
Translation
According to the 2025 National Medical Radiation Assessment Yearbook published by the 질병관리청, the number of medical radiation examinations performed on the public last year was 431.59 million in total, or 8.4 per person. That is a level 4.6% higher than the year before. The number of examinations rose about 29.6% from 333.13 million in 2021 (6.4 per person) to 431.59 million in 2025, and over the same period the radiation dose received also rose about 22.6%, from 2.64 to 3.24 man-sieverts per person. By type, plain X-ray imaging was the most common, at 329.6 million examinations, or 76.4% of the total. CT, by contrast, was only 3.8% of examinations at 16.33 million, yet accounted for 67.1% of the total dose. The 질병관리청 explained that the use of medical radiation examinations keeps expanding because of advances in medical technology, population ageing and the spread of health check-ups.

Grammar points
N에 따르면according to N
에 따르면 follows the name of a source — a report, an agency, a survey — and marks everything after it as coming from that source. Korean news opens statistical stories with this phrase almost by rule, because it tells the reader who is responsible for the numbers before the numbers arrive. The sentence that follows usually ends in a plain statement, not in -다고 한다, since the attribution has already been made.
Example: 질병관리청이 발간한 '2025년 국민 의료방사선 평가 연보'에 따르면, 지난해 국민의 의료방사선 검사 건수는 총 4억 3159만 건으로 국민 1인당 8.4건이었습니다.
According to the 2025 National Medical Radiation Assessment Yearbook published by the 질병관리청, the number of medical radiation examinations performed on the public last year was 431.59 million in total, or 8.4 per person.
N에 불과하다to be only N, to be no more than N
불과하다 after a number or amount says that the figure is small, and it always carries the writer's judgement that it is smaller than one might expect. 검사 건수의 3.8%에 불과하지만 is although it is only 3.8% of examinations; the -지만 that follows sets up the contrast with the much larger share of the dose. This is the standard way Korean reporting builds a small-share-but-large-effect sentence.
Example: 반면 CT는 1633만 건으로 검사 건수의 3.8%에 불과하지만, 전체 피폭선량의 67.1%를 차지했습니다.
CT, by contrast, was only 3.8% of examinations at 16.33 million, yet accounted for 67.1% of the total dose.
-(으)ㄴ 수준이다to be at the level of ..., to amount to ...
수준 means level, and a clause in the -(으)ㄴ modifier form before 수준이다 describes a figure by placing it on a scale: 전년보다 4.6% 늘어난 수준이다 is a level 4.6% higher than the previous year. Writers use it instead of a bare 늘었다 when they want to present the number as a measured position rather than an event, which gives a statistical sentence a slightly more detached tone.
Example: 이는 전년보다 4.6% 늘어난 수준입니다.
That is a level 4.6% higher than the year before.
