Carbon-14 dating, also called radiocarbon dating, method of age determination that depends upon the decay to nitrogen of radiocarbon (carbon-14).

What radioactive isotope is used for dating?

isotope carbon-14 Another important atomic clock used for dating purposes is based on the radioactive decay of the isotope carbon-14, which has a half-life of 5,730 years. Carbon-14 is produced continuously in the Earths upper atmosphere as a result of the bombardment of nitrogen by neutrons from cosmic rays.

Can you swim in a nuclear reactor pool?

Even though the pools of water surrounding nuclear reactor cores look radioactive, they usually contain less radiation than the surrounding air. So unless youre swimming in the water directly surrounding a nuclear core, youre going to be fine.
