Ways to celebrate

Wilhelm Röntgen stumbled onto X-rays by accident, noticed an unexplained glow in his lab, and rather than patenting a discovery that would reshape medicine, he chose to let the whole world use it for free.

Recognize the field

Celebrate by:

  • Thanking a radiologic technologist or radiologist you know for the work they do.
  • Looking into how X-ray imaging has evolved since 1895, from early exposures to modern digital scans.
