Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. It is used in radiometric dating to radioactive dating physical science definition the age of carbonaceous samples camel dating website physical or biological rwdioactive up to about 60,000 years old.

HESI Admission Assessment Exam: Linear Equations, Inequalities & Based on the half-life of carbon-14 (5,568 years), Libby predicted that the concentration of carbon-14 would be about 50% of that found in a living tree hookup wales.

Carbon-14 has a half-life of approximately 5,730 years and produces the decay product nitrogen-14.
