At their core, radiometric dating relies on various aspects of physics and chemistry, so sometimes the "validation" comes from the basic underpinnings of the method.
The method of radiocarbon dating of cremated bones was tested by dating paired samples of bone and associated context materials such as pitch, charcoal and a dendrochronologically dated oak coffin.
The dating of these paired test samples were largely performed as blind tests and showed excellent agreement between pitch and bone.
Recent puzzling observations of tiny variations in nuclear decay rates have led some to question the science of using decay rates to determine the relative ages of rocks and organic materials.
Scientists from the National Institute of Standards and Technology (NIST), working with researchers from Purdue University, the University of Tennessee, Oak Ridge National Laboratory and Wabash College, tested the hypothesis that solar radiation might affect the rate at which radioactive elements decay and found no detectable effect.
Are there experiments done to test the solidity of the dates for various things?
Could i give 2 samples of rock to a geochronologist (both of which are different ages) without any context in a blind experiment and get accurate results as to which rock sample is older and by roughly how much?
This in and of itself can tell us interesting things about the history of the zircon and the rock from which it came.
Depends on the technique, both in terms of whether the "blind taste test" approach would work and the amount of error.
The maximum neutrino flux in the sample in their experiments was several times greater than the flux of neutrinos from the sun.
The researchers followed the gamma-ray emission rate of each source for several weeks and found no difference between the decay rate of the spheres and the corresponding foils.
The unswerving regularity of this decay allows scientists to determine the age of extremely old organic materials -- such as remains of Paleolithic campfires -- with a fair degree of precision.
