Rated 4.63/5 based on 626 customer reviews

Radiocarbon dating is used to determine the age of carbonaceous materials up to about 60,000 years old.

After about 50,000- 60,000 years (or approximately nine half-lives) the amount of C-14 remaining is generally too small to measure reliably.

Its presence in organic materials is the basis of radiocarbon dating to date archaeological, geological and hydrogeological samples.$720\cancel\times \dfrac= 30\, days \nonumber$ $n=3 =\dfrac \nonumber$ $\text = \dfrac (8.0 \, ug) \nonumber$ After 720 hours, 1.0 ug of the material remains as $$\ce$$-225 .For example, carbon-14 has a half-life of 5,730 years and is used to measure the age of organic material.Interactive Simulation: Visualizing Half-Life Click on this interactive simulation to visualize what happens to a radioisotope when it decays.and learn about different types of radiometric dating, such as carbon dating.
