*•58 Two radioactive materials that alpha decay, 238U and 232Th,
and one that beta decays, "K, are sufficiently abundant in granite
to contribute significantly to the heating of Earth through the de-
cay energy produced. The alpha-decay isotopes give rise to decay
chains that stop when stable lead isotopes are formed. The isotope
4"K has a single beta decay. (Assume this is the only possible decay of
that isotope.) Here is the information:
