The half-life of strontium refers to the time it takes for half of a sample of a radioactive isotope of strontium to decay. The most commonly referenced isotope is strontium-90, which has a half-life of about 28.8 years. This isotope is a byproduct of nuclear fission and is of particular concern in nuclear safety and environmental studies. Other isotopes of strontium have different half-lives, but strontium-90 is the most notable in discussions of radioactivity.
Strontium-90 (90Sr) is a radioactive isotope of strontium, with a half life of 28,79 years.
The time it takes for half of the rubidium atoms in a sample to change into strontium is determined by the half-life of rubidium-87, which is approximately 48.8 billion years. This means that it would take about 48.8 billion years for half of the rubidium-87 atoms to decay into strontium-87.
The time it takes for the radiation level of strontium to drop to one-sixteenth of its original level can be determined using its half-life. For strontium-90, which has a half-life of about 29 years, it would take four half-lives for the radiation to decrease to one-sixteenth (since (1/2^4 = 1/16)). Therefore, it would take approximately 116 years for the radiation level of strontium-90 to drop to one-sixteenth of its original level.

Strontium-88 It is the closest to the Strontium atomic mass.
Strontium-90 (90Sr) is a radioactive isotope of strontium, with a half life of 28,79 years.
After 65.2 days, half of the original amount of strontium-85 will remain, so 5 grams will be left.
50.6 days
The time it takes for half of the rubidium atoms in a sample to change into strontium is determined by the half-life of rubidium-87, which is approximately 48.8 billion years. This means that it would take about 48.8 billion years for half of the rubidium-87 atoms to decay into strontium-87.
The half-life of rubidium-87 is approximately 48.8 billion years. This means it would take about 48.8 billion years for half of the rubidium-87 atoms in a rock sample to decay into strontium-87. Therefore, to see half of the rubidium-87 atoms change into strontium-87, you would need to wait this extensive period.

If the half-life of strontium-90 is around 29 years, then if 3.0 grams remained in 1989, there would have been approximately 6 grams in 1933. This is because each half-life represents a halving of the original amount.
The time it takes for the radiation level of strontium to drop to one-sixteenth of its original level can be determined using its half-life. For strontium-90, which has a half-life of about 29 years, it would take four half-lives for the radiation to decrease to one-sixteenth (since (1/2^4 = 1/16)). Therefore, it would take approximately 116 years for the radiation level of strontium-90 to drop to one-sixteenth of its original level.

Strontium occurs naturally in the minerals celestite and strontianite. The 90Sr isotope is present in radioactive fallout and has a half-life of 28.90 years. Due to its extreme reactivity to air, this element occurs naturally only in compounds with other elements, as in the minerals strontianite, celestite, etc. Strontium is isolated as a yellowish metal and is somewhat malleable. Strontium is chiefly employed (as in the nitrate) to color pyrotechnic flames red.
