half-life
Time required for half of a quantity of particle-emitting material to undergo radioactive decay. Because emission slows as the isotope decreases in radioactivity, taking half the life of its decay is more meaningful than trying to estimate the entire amount. Half-lives range from millionths of a second to millions of years.
