We are told that these methods are accurate to a few percent, and that there are many different methods.
We are told that of all the radiometric dates that are measured, only a few percent are anomalous.
Radiometrically measured age of meteorites, and is also about 500,000,000..
Even the creationist accounts that I have read do not adequately treat these issues.
At the start, let me clarify that my main concern is not the age of the earth, the moon, or the solar system, but rather the age of life, that is, how long has life existed on earth.
Some historically significant uses of the method include the dating of late Pleistocene and Holocene era artifacts and determining when major geologic events occurred.
Some radioactive dating, especially carbon dating, cannot be entirely exact in its age estimates.
The level of carbon radioisotopes in the atmosphere in ancient times could have fluctuated, meaning that the radioisotope's decay rate is not always predictable.
For example, during historic eras where there is a high level of carbon radioisotopes in the atmosphere, more radioisotopes would have been present in an object than in an object that originated during a period of low atmospheric carbon radioisotope levels.
Calculating the age of an item is computed after using a mass spectrometer to analyze the make-up of the object -- looking for and determining the number of daughter isotopes in the object.
Scientists then use the predictable rate of decay of that daughter's parent radioisotope to determine the length of time required to produce that many daughter isotopes.
) Shortly after the discovery of the neutron in , Enrico Fermi realized that certain rare betadecay reactions immediately yield neutrons as a decay particle (neutron emission).
Age "uncertainty" When a "simple" dating method is performed, the result is a single number. Also, an increase in the solar wind or the Earths magnetic field above the current value would depress the amount of carbon14 created in the atmosphere. Crosschecks between different isotopes with different chemical properties.
How radiometric dating works in general : Response: Solely by the migration of radiogenic 87Sr among the. Radiometric dating has been carried out since when it was invented by Ernest Rutherford as a method by which one might determine the age of the Earth.
