What is radioactive dating?

Answer 1

Radioactive dating is a technique used to find how old an object is.

One such example is potassium-argon dating, where potassium decays into argon. The proportion of potassium to argon suggests how old the object in question is.

An equation used is t = (1/c)Ln(1+(D/P)) Where c is the decay constant D is number of daughter atoms (number decayed) P is the number of parent atoms (number undecayed) t is the age of the object.

Another common technique in dating an object is carbon dating. Because the amount of carbon-14 has remained roughly constant through time on the earth it is possible to calculate the age of an object by finding the proportion of carbon-14 to carbon-12.

There is a suspicion that the relative abundance of carbon-14 could be changing due to the thinning of the ozone layer. The amount of carbon-14 depends on the amount of radiation permeates the ozone and thus the amount could be changing. Not proven, only a hypothesis.
Accuracy radioactive dating is called radiometric dating. This is taught in Biology.

Answer 2

A radioactive isotope is an atom unstable, which emit nuclear radiation.
Radioactive dating is based on the properties of radioactive isotopes, essentially half life and radioactive decay.

Answer 3

It's radiocarbon dating, and it's finding out how old something is using radiocarbon.

Answer 4

It is used to determine the age of an object by measuring the amount of a certain radioisotope remaining in that object.

Answer 5

it is used a special carbon called carbon 14 oh yea ialmost for got call me if u want to have sex on 403-923-1111

Answer 6

the use of radioisotopes to determine the age of something. APEX USERS
