Radio-luminescent paints and signage, lantern mantles, vibrant ceramic glazes, and potassium-based salt alternatives are a few examples of items that contain radioactive substances.
An unstable radioactive material emits harmful radiation types. It is radioactive substances unstable because the electric force that seeks to separate the atom's nucleus from the rest of the atom is stronger than signage the strong nuclear force holding it together. The atoms will transform into more stable ones as a result of its instability.
Radioactivity can also be thought of in terms of energy. A radioactive atom radioactive substances contains more energy than it requires. When something has more energy than it requires, it will eventually lose signage that energy since the universe's energy tends to disperse. Energy in the universe cannot be generated or destroyed, therefore when a radioactive atom loses its excess energy through decay, it must go somewhere.
