During nuclear explosion one of the products is `^90Sr` with half life of 28.1 years. If `1 mug` of `^90Sr` 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 lost metabolically?

During nuclear explosion, one of the products is ^90Sr with half-line of 28.1 years. If 1 mug of ^90Sr 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.

The half life of 38^90Sr is 29 years. What is the disintegration rate of 25 mg of this isotope?
