363974 Half-life of a radioactive substance is 5 min. The time between 20% and 80% decay will be:

363975 For a radioactive material, half-life is 10 minutes. If initially there are 600 number of nuclei, the time taken (in minutes) for the disintegration of 450 nuclei

363976 A radioactive isotope has a half-life of \(T\,yr\). How long will it take the activity to reduce to \(1 \%\) of its original value?

363977 After 300 days, the activity of a radioactive sample is 5000 \(dps\) (disintegration per second). The activity becomes 2500 \(dps\) after another 150 days. The initial activity of the sample (in \(dps\)) is
