Please give a brief explanation of how X-rays were discovered and how they are produced.
In the late 1890s many people had x rays taken of their body. X-ray machines were common in shoe stores in the late 1940s and early 1950s for people to examine how their shoes fi t; customers enjoyed seeing pictures of their bones. Discuss the safety of these undertakings.
