What is Sr-90 used for?
What is Sr-90 used for?
Strontium-90 is used as a radioactive tracer in medical studies and in studies of agricultural crops. It is also used in beacons for navigating, remote weather stations and space vehicles. Strontium-90 is used in electron tubes to treat eye diseases and as a radiation source in industrial thickness gauges.
What type of radiation does strontium-90 emit?
beta radiation
It emits only beta radiation with a short range, which makes it harmful if swallowed or inhaled. In this case, it may be the source of bone cancers and leukaemias if the spinal cord is involved. In food, milk and calcium-rich cheese favour strontium.
Where is strontium-90 found?
nuclear reactors
Strontium-90 is found in the liquid waste stream of nuclear reactors, but is not released to the environment during normal nuclear reactor operations.
What is decay scheme of Sr-90?
Strontium- 90 decays to yttrium-90, which in turn decays to stable zirconium. The isotopes of strontium and yttrium emit beta particles as they decay.
Does strontium cause kidney stones?
X-ray fluorescence analysis clearly shows that strontium co-localizes with calcium in calcium based stone formation. In addition, the kidneys process strontium similarly to calcium. The amount of strontium and apatite in kidney stones is correlated.
How is strontium-90 created?
Strontium-90 is produced commercially through nuclear fission. Fissioning that occurs without any outside cause is called “spontaneous fission.” for use in medicine and industry. It also is found in the environment from nuclear testing that occurred in the 1950s and 1960s as well in nuclear reactor waste.

How is Sr-90 produced?
How was strontium-90 discovered?
History of Strontium-90 Origin Sr was discovered in the 1940s. It was one of the many radioactive isotopes discovered during the nuclear experiments performed during development of the nuclear bomb.
Who should not take strontium?
A specific prescription form of strontium, strontium-89, is LIKELY UNSAFE during pregnancy and breast-feeding. It is a radioactive material that might harm the fetus. It may also pass into breast milk and could harm a nursing infant. Heart disease: Don’t use strontium if you have high blood pressure or heart disease.
Is strontium safe to take?
You do not know what amounts your body is getting when you take these supplements. You also do not know whether they can seriously harm you. Research from Europe suggests that patients on strontium ranelate may have an increased risk of heart attacks[1,3], blood clots,[1, 3] and serious skin reactions (DRESS syndrome).
