Quizplus · Accepted Answer

The half-life is the time it takes for half of the radioactive material to decay. It is a measure of the rate of decay of a substance and is used to determine the absolute age of rocks and other materials. The other options (absolute age, date age, true-life) are not commonly used terms in radioactive decay and do not accurately describe the concept of half-life.
