Question: Naturally, occurring samarium includes 15.1% of the radioactive isotope^147Sm, which decays by alpha emission. One gram of natural Sm gives 89 plusminus 5 alpha decays

Naturally, occurring samarium includes 15.1% of the radioactive isotope^147Sm, which decays by alpha emission. One gram of natural Sm gives 89 plusminus 5 alpha decays per second. From these data calculate the half-life of the isotope^147Sm and give its uncertainty.
