How is radioactive half-life defined quizlet
WebHalf life is defined as the. time taken for half of the radioactive nuclei now present to decay. A short half life means the. activity fall quickly because lots of nuclei decay in a short time. A long half life means the. activity falls more slowly because the nuclei don't decay … WebRadioactive decay reduces the number of radioactive nuclei over time.
