Sr. ) is a radioactive isotope of strontium produced by nuclear fission, with a half-life of 28.8 years. It undergoes β − decay into yttrium-90, with a decay energy of 0.546 MeV. [2] Strontium-90 has applications in medicine and industry and is an isotope of concern in fallout from nuclear weapons, nuclear weapons testing, and nuclear accidents.

Feb 5, 2024 · Strontium-90 is a man-made radioactive form of strontium that is widely dispersed in the environment and the food chain from nuclear testing and waste. It can cause cancers of the bone, bone marrow, and soft tissues around the bone if inhaled or ingested. Learn more about its sources, half-life, and health effects.
Sr-90 is a soft metal used as a power source or in medicine and industry. It can cause bone cancers and emit beta radiation that can burn eyes and skin. Learn more about its sources, forms, and health effects.

Strontium-90 is a radioactive isotope produced in nuclear fission and fallout. It decays by beta emission and can cause bone and tooth damage. See its mass, half-life, decay mode, isotones and isobars.
Strontium-90 behaves like calcium in the human body and tends to deposit in bone and blood-forming tissue (bone marrow). Thus, strontium-90 is referred to as a "bone seeker," and exposure will increase the risk for several diseases including bone cancer, cancer of the soft tissue near the bone, and leukemia.
Jan 6, 2017 · Strontium-90 is a radioactive form of strontium produced by nuclear fission and testing. It can cause bone cancers and is slowly decaying in the environment. Learn more about its sources, health effects, and decay from US EPA.
