Carbon dating used for

Other useful radioisotopes for radioactive dating include Uranium -235 (half-life = 704 million years), Uranium -238 (half-life = 4.5 billion years), Thorium-232 (half-life = 14 billion years) and Rubidium-87 (half-life = 49 billion years).The use of various radioisotopes allows the dating of biological and geological samples with a high degree of accuracy.­ ­As soon as a living organism dies, it stops taking in new carbon.

Volcanoes spew out CO which could just as effectively decrease the ratio.

However, there is strong evidence which suggests that radioactive decay may have been greatly accelerated in the unobservable past.

We must also assume that the ratio of C-12 to C-14 in the atmosphere has remained constant throughout the unobservable past (so we can know what the ratio was at the time of the specimen's death).

This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature.

C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14.

However, radioisotope dating may not work so well in the future.
