Radiometric measurement is based on the decay of certain elements, the rate of which is a known scientific fact.
Radiometric dating is the term for a method to determine the age of an object based on the concentration of a particular radioactive isotope contained within it. Example sentence:One of the early tests of radiometric dating was to estimate the age of the wood from an ancient Egyptian artifact, for which the age was already known from historical documents.
This is known as radiometric dating.
Argon is a gas that may leak from a sample and provide inaccurate data
- Potassium-Argon method – Potassium-40 decays to argon and calcium.- Uranium-Lead method- Rubidium-Strontium method- Carbon-14 method – also known as carbon dating. The half-life of carbon-14 is only 5, 730 years so this method is mainly used for dating things from the last 50,000 years
The uranium-lead method
Radio metric dating.
Radiometric measurement is based on the decay of certain elements, the rate of which is a known scientific fact.
Radiometric dating is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and can be used to date a wide range of natural and man-made materials.
What method, and what materials, are best for dating depends on what exactly you are after.

Carbon-14 dating would be the most appropriate radiometric dating method for dating artifacts found at effigy mounds. This method is commonly used for dating organic materials such as wood, charcoal, or bone, which are typically found in archaeological sites like effigy mounds.
carbon 14 dating
Radiocarbon dating is an absolute, (it is used provides a calender year/s for a particular event), radiometric (it is based on the known decay rate of a radioactive isotope) dating method.
