The half-life of carbon-14 is known to be 5,730 years, so we can use the half-life formula to calculate the elapsed time, or age of the material. Half-Life Formula for Time Elapsed By rearranging the half-life formula, we can solve for the amount of time elapsed by comparing the ...
half-life (haf'līf), The period in which the radioactivity or number of atoms of a radioactive substance decreases by half; similarly applied to any substance, such as a drug in serum, whose quantity decreases exponentially with time. Compare:half-time. ...
half-life n 1.(General Physics) the time taken for half of the atoms in a radioactive material to undergo decay. Symbol:τ 2.(Biology) the time required for half of a quantity of radioactive material absorbed by a living tissue or organism to be naturally eliminated (biological half-life...
We have measured the half-life of O, a superallowed (0→0) β decay isotope. The O was produced by the C(He,n)O reaction using a carbon aerogel target. A low-energy ion beam of O was mass separated and implanted in a thin beryllium foil. The beta particles were counted with plast...
