Two different radioactive isotopes are produced by neutron activation at the same constant rate. Their half-lives are different, and initially neither isotope is present. Which statement is correct?

Question

Answer

Their activities are always equal because their production rates are equal.

Answer

Both isotopes reach the same saturation activity, but the isotope with the shorter half-life approaches saturation faster.

Answer

The isotope with the longer half-life always has the greater activity during irradiation.

Answer

The isotope with the shorter half-life always has fewer radioactive atoms present at the end of irradiation, regardless of the irradiation duration.

Answer

I choose not to answer.
