Strontium 90 radioactivity

WebStrontium-90 is formed in nuclear reactors or during the explosion of nuclear weapons. Radioactive strontium generates beta particles as they decay. One of the radioactive properties of strontium is half-life, or the time it takes for half of the isotope to give off its radiation. It is used in fireworks, red signal flares, and tracer bullets. WebOct 31, 2024 · Strontium-90 is formed by nuclear explosions and is considered to be the most dangerous component of nuclear fallout by the federal Agency for Toxic Substances and Disease Registry.
