Half Life Questions at Life

Half Life Questions. Irrespective of the amount present at a time, it will always be halved after one. After 2 days, 5 grams of the radioisotope remains unchanged.

The quantities available here are, λ = 0.002 1/years consequently, the half life equation becomes: \(t\frac{1}{2}\) = 0.693/ λ \(t\frac{1}{2}\) = 0.693/0.002 = 346.5 The activity of a source drops from 1000 kbq to 125 kbq in 9 days.

An 80 milligram sample of a radioactive isotope decays to 5 milligrams in 32 days. What fraction of the atoms willhave decayed after 6 hours? Calculate the half life of the source. 1 year divided by 2 is half a year or 6 months;
