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.

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).

No matter when Kennewick Man died, his bones were exposed to the flooding of the Columbia River, plus the bones were exposed to rain, humidity, moisture in the soil (i.e.
