Question
The initial activity of a radioactive sample is 120 Bq. If after 24 h the activity is measured to be 15 Bq, find the half-life of the sample.
Step 1
Step 1: The activity of a radioactive sample is given by the formula: \[A = A_0 e^{-\lambda t}\] where \(A\) is the final activity, \(A_0\) is the initial activity, \(\lambda\) is the decay constant, and \(t\) is the time elapsed. Show more…

A radioactive sample has an initial activity of 1280 decays/s. Its activity 40 hours later is 680 decays/s. What is its half-life?
The activity of a sample containing radioactive $^{108} \mathrm{Ag}$ is $6.4 \times 10^{4}$ Bq. Exactly 12 min later, the activity is $2.0 \times 10^{3} \mathrm{Bq} .$ Calculate the half-life of $^{108} \mathrm{Ag} .$
