One of the interesting applications of radioactive decay is the technique of radioactive dating.
The most common of these medical procedures involve the use of x-rays — a type of radiation that can pass through our skin.
Additionally, elements may exist in different isotopes, with each isotope of an element differing in the number of neutrons in the nucleus.
Although scientists have only known about radiation since the 1890s, they have developed a wide variety of uses for this natural force.
Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied.
All ordinary matter is made up of combinations of chemical elements, each with its own atomic number, indicating the number of protons in the atomic nucleus.
