Quick Summary

Characteristic X-rays are electromagnetic radiation with very short wavelengths, typically ranging from 10^-8 to 10^-12 meters. They are produced when electrons strike a metal target, causing atoms to emit X-rays with specific wavelengths that are unique to that element.123

These X-rays are a form of ionizing radiation, meaning they have enough energy to remove electrons from atoms. While this property makes them valuable for medical imaging and cancer treatment, it also means they can cause damage to living cells and genetic material with prolonged exposure. The discovery of X-rays by Wilhelm Conrad Röntgen in 1895 revolutionized physics and medicine, opening doors to understanding the atomic world and developing new diagnostic tools.13

Production of X-rays
This “characteristic radiation” results from the excitation of the target atoms by collisions with the fast-moving electrons. Most commonly, a collision first causes a tightly bound inner-shell electron to be ejected from the atom; a loosely bound outer-shell electron then falls into the inner shell to…
