Radioactive Decay Rates Not Stable - Article
/article/radioactive-decay-rates-not-stable
Brian Thomas, Ph.D. - ... about a century, radioactive decay rates have been heralded as steady and stable processes that can be reliably used to help measure how old rocks are. They helped underpin belief in vast ages and had largely gone unchallenged. But certain decay...

The Age of the Earth's Atmosphere Estimated by its Helium Content - Article
/article/age-earth-atmosphere-helium
Larry Vardiman, Ph.D. - ... the earth is billions of years old, the radioactive production of helium in the earth’s crust should have added a large quantity of helium to its atmosphere. Current diffusion models all indicate that helium escapes to...

The Sun Alters Radioactive Decay Rates - Article
/article/sun-alters-radioactive-decay-rates
Brian Thomas, Ph.D. - ... scientists rely on the assumption that radioactive elements decay at constant, undisturbed rates and therefore can be used as reliable clocks to measure the ages of rocks and artifacts. Most estimates of the age of the earth are founded on this...

Revisiting the Isochron Age Model, Part 1 - Article
/article/revisiting-isochron-age-model-part-1
Vernon R. Cupps, Ph.D. - ... dating is based on the decay rate of a starting radioactive isotope (the parent) into its stable counterpart (the daughter). An age is assigned to an object by measuring the quantity of each isotope and calculating how long it would...

Fluctuations Show Radioisotope Decay Is Unreliable - Article
/article/fluctuations-show-radioisotope-decay
Brian Thomas, Ph.D. - ... isotopes are commonly portrayed as providing rock-solid evidence that the earth is billions of years old. Since such isotopes are thought to decay at consistent rates over time, the assumption is that simple measurements can lead to...
