Although Tesla gave Roentgen full credit for the finding, Roentgen congratulated Tesla on his sophisticated images, wondering how he had achieved such impressive results (,Fig 4) (,7).

How many xrays are safe in a lifetime?

The more scans you have, the higher your lifetime exposure and therefore the higher your risk. The American College of Radiology recommends limiting lifetime diagnostic radiation exposure to 100 mSv. That is equal to 10,000 chest x-rays or up to 25 chest CTs.

Why are they called X-rays?

How were xrays created?

Before their discovery in 1895, Xrays were just a type of unidentified radiation emanating from experimental discharge tubes. This voltage accelerated the electrons coming from the cathode to a high enough velocity that they created Xrays when they struck the anode or the glass wall of the tube.

How did X-rays impact the world?

Xrays were viewed as very valuable technology for more than just swallowed pennies and digested food. They were revered in the medical community their ability to diagnose tuberculosis.
