Dating rocks using radioactive decay

Rubidium-Strontium dating: The nuclide rubidium-87 decays, with a half life of 48.8 billion years, to strontium-87.

Strontium-87 is a stable element; it does not undergo further radioactive decay.

Therefore the amount of argon formed provides a direct measurement of the amount of potassium-40 present in the specimen when it was originally formed.

Because argon is an inert gas, it is not possible that it might have been in the mineral when it was first formed from molten magma.

Potassium-Argon dating: The element potassium (symbol K) has three nuclides, K39, K40, and K41. K40 can decay in two different ways: it can break down into either calcium or argon.

The ratio of calcium formed to argon formed is fixed and known.

C and counting the amount of each) allows one to date the death of the once-living things.

Using the decays of uranium and thorium, our galaxy has been found to be between 10 and 20 billion years old and the earth has been found to be 4.6 billion years old. Within experimental error, this estimate agrees with the 15 billion year estimate of the age of the Universe.

The man's body was recovered and pieces of tissue were studied for their C content by accelerator mass spectroscopy.

The best estimate from this dating technique says the man lived between 33 BC. From the ratio, the time since the formation of the rock can be calculated.

Radiometric dating is a means of determining the "age" of a mineral specimen by determining the relative amounts present of certain radioactive elements.

By "age" we mean the elapsed time from when the mineral specimen was formed.

The sum of protons plus neutrons is the mass number.
