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

Radioactive dating is a technique used to determine the age of an object by measuring the amount of a radioactive isotope it contains. By comparing the ratio of parent isotope to daughter isotope, scientists can calculate the age of the sample. This method is commonly used in geology, Archaeology, and anthropology to date rocks, fossils, and artifacts.

Answer 3

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 4

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

Answer 5

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

Answer 6

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
