QUESTION:
In the nuclear industry, workers use a rule of thumb that the radioactivity from any sample will be relatively harmless after 10 half-lives. Calculate the fraction of a radioactive sample that remains after this time period. (Hint: Radioactive decays obey first-order kinetics.)
ANSWER:
Step 1 of 3
We know the radioactive decays obeys first order kinetics
We need to find the fraction remaining after half life of a radioactive decay.
Half life of a first order reaction is
