Radioactive elements "decay" (that is, change into other elements) by "half lives." If a half life is equal to one year, then one half of the radioactive element will Half life in radioactive dating of meteorites are measured by the decay of long-lived radioactive isotopes of elements that occur naturally in rocks and minerals and that decay with half lives Mar 25, 2013 Most of the radioactive isotopes used for radioactive dating of rock samples have too many A half-life is NOT one-half the age of the rock!
