International Day of Radiology – November 8, 2023

The International Day of Radiology (IDoR) is a yearly event commemorated on November 8, the anniversary of the discovery of x-rays, and promotes radiology’s role in healthcare. The European Society of Radiology (E.S.R.), the Radiological Society of North America, and the American College of Radiology (A.C.R.) jointly launched it in 2012. Nearly 200 national sub-specialty and allied organizations around the world recognize and celebrate the International Day of Radiology. Every year, a theme is chosen that focuses on various radiology specialties.

History of International Day of Radiology

Radiology, a discipline of medicine, utilizes medical imaging to diagnose and treat diseases that affect both animals and humans. On November 8, 1895, Wilhelm Conrad Röntgen, a German mechanical engineer and physicist, discovered x-rays by accident while exploring cathode rays, thereby establishing the groundwork for the medical specialty of radiology. Röntgen went on to discover and create electromagnetic radiation in the X-ray or Röntgen ray wavelength range, earning him the Nobel Prize in Physics in 1901.

The International Day of Radiology was established in 2011 as a follow-up to the European Day of Radiology. On February 10, 2011, the first and only European Day of Radiology (EDoR) was conducted to honor the anniversary of Röntgen’s death. The European Society of Radiology hosted the event. Following the European Day of Radiology’s success, the E.S.R. collaborated with the Radiological Society of North America and the American College of Radiology to create the International Day of Radiology. It was also determined that the anniversary of Röntgen’s death should be relocated to the anniversary of his discovery of the x-ray.

On November 28, 2011, the three founding societies formally recognized the day during the annual Radiological Society of North America meeting in Chicago. November 8 was eventually picked, and all radiological organizations around the world commemorate it.

    Thank a radiographer or radiologist for their services. If you have a personal radiographer, you can express your gratitude by sending them an edible arrangement or a thank-you letter.

  3. Research and learn about radiography

    Learn more about radiation and how it is used to create x-rays. Continue your research by learning about Marie Curie and Raymond's contributions to radiology. Use the hashtag #WorldRadiographyDay to raise awareness about this day on social media.

5 Interesting Facts About Radiology

  1. X-ray procedure in America

    In the United States, about 150 million x-ray procedures are performed each year.

  2. Radiologic nun technologists

    Nuns made up 37% of radiologic technologists in 1927.

  3. Over 330,000 radiologic technologists

    There are over 330,000 radiologic technologists in the United States.
