During nuclear explosion, one of the products is`""^(90_(Sr))` with half-life of 28.1 years. If 1µg 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.

`t_(1//2)=6.93` years
`t=(2.303)/(k) log""(100)/(10) rArr k =(0.693)/(6.93) =0.1 rArr t=(2.303)/(1) xx1 =23.03` years
