Half life of 90Sr is 6.93 years. In a child body 1 g of 90Sr dopped in place of calcium, how many years will it take to reduce its concentration by 90% (Assume no involvement of Sr in metabolism)

Half life of 90Sr is 6.93 years. In a child body 1g of 90Sr dopped in place of calcium, how many years will it take to reduce its concentration by 90% (Assume no involvement of Sr in metabolism)

Half life of 90Sr is 6.93 years. In a child body 1 mg of 90Sr dopped in place of calcium, how many years will it take to reduce its concentration by 90% (Assume no involvement of Sr in metabolism)

During the nuclear explosion, one of the products is ._(90)Sr with half life of 6.93 years. If mug" of "._(90)Sr was absorbed in the bones of a newly born in place of Ca, how much time (in years) is required to reduce it by 90% . If it is not lost metabolically? Report your answer by rounding it up to a nearest whole number.

Half-life of radium is 1500 y. In how many years will 1 g of pure radium reduce by 1 mg ?

During nuclear explosion, one of the products is .^(99)Sr with half - life of 28.1 years. If 1 mug of .^(90)Sr was absorbed in the bones of a newly born baby instead of calcium, how much of its will remain after 10 years and 60 years if it is not lost metabolically.

During nuclear explosion, one of the products is .^(99)Sr with half - life of 28.1 years. If 1 mug of .^(90)Sr was absorbed in the bones of a newly born baby instead of calcium, how much of its will remain after 10 years and 60 years if it is not lost metabolically.

During nuclear explosion, one of the products is 90_{Sr} with half-life of 28.1 years. If 1 mu g of 90_{Sr} was absorbed in the bones of a newly born baby instead of calcium, how much of it will remain after 10 years and 60 years if it is not lost metabolically.
