A beta particle (symbol β) is a high-speed and high-energy electron which is emitted by radioactive decay of the atomic nucleus during process of the beta decay.
Strontium-90 is material which is most commonly used to produce the beta particles.
Beta particles are used to treat conditions such as eye as well as bone cancer.
Eutrophication is the enrichment of a body of water with excessive nutrients (nitrogen and phosphorus), which causes algal growth and subsequent decline of dissolved oxygen after decomposition.
