World Radiography Day: Let us remember Wilhelm Roentgen for discovery of X – RAYs.

World Radiography Day is celebrated on 8 November every year. The purpose of World Radiography Day is to raise public awareness of radiographic imaging and therapy, which play a crucial role in the diagnosis and the treatment of patients and, most importantly, ensuring radiation is kept to the minimum required, hence improving the quality of patient care. The date marks the anniversary of the discovery of x-radiation by Wilhelm Roentgen in 1895.  His investigations and the resulting paper, “On a New Kind of Rays,” took the world by storm, revolutionized medicine, and earned him the first Nobel Prize in Physics in 1901

Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. It is used to diagnose or treat patients by recording images of the internal structure of the body to assess the presence or absence of disease, foreign objects, and structural damage or anomaly. During a radiographic procedure, an x-ray beam is passed through the body.


Radiography is used in many types of examinations and procedures where a record of a static image is desired. Some examples include

  • Dental examination.
  • Verification of correct placement of surgical markers prior to invasive procedures.
  • Mammography.
  • Orthopedic evaluations.
  • Spot film or static recording during fluoroscopy.
  • Chiropractic examinations.



  • Noninvasively and painlessly help to diagnose disease and monitor therapy.
  • Support medical and surgical treatment planning.
  • Guide medical personnel as they insert catheters, stents, or other devices inside the body, treat tumors, or remove blood clots or other blockages.

While X-rays are linked to a slightly increased risk of cancer, there is an extremely low risk of short-term side effects. Exposure to high radiation levels can have a range of effects, such as vomiting, bleeding, fainting, hair loss, and the loss of skin and hair. However, X-rays provide such a low dose of radiation that they are not believed to cause any immediate health problems.
