Flaws in radiometric dating

For example, a team at Purdue University in Indiana was monitoring a lump of manganese-54 in a radiation detector box to measure the isotope’s half-life.

At PM on December 12, 2006, the instruments recorded a sudden dip in radioactivity.

There are a variety of ways of doing this; here is a common method.

Radioactive elements, such as rubidium-87 (but not strontium-86 or strontium-87), decay over time.

By evaluating the concentrations of all of these isotopes in a rock sample, scientists can determine what its original make-up of strontium and rubidium were.

Continue reading The most widely used tool to measure the age of the Earth is radioactive decay.

The great scientist Ernest Rutherford was the first to define the concept of “half-life,” that is, the time it takes for one half of the atoms in a given quantity of a radioactive element (such as plutonium) to decay into another element (such as uranium), or for one isotope of an element (such as carbon-14) to decay into another isotope of that same element (such as carbon-12).
