Radioactive dating facts

the pattern was caused by the way the magma was emplaced or how it crystallized. But Drs Humphreys and Baumgardner realized that in other cases there were many independent lines of evidence that suggested that huge amounts of radioactive decay had indeed taken place.

(These include the variety of elements used in ‘standard’ radioisotope dating, mature uranium radiohalos and fission track dating.) It would be hard to imagine that geologic processes alone could explain all these.

A material containing such unstable nuclei is considered radioactive.

If there are multiple particles produced during a single decay, as in beta decay, their relative angular distribution, or spin directions may not be isotropic.

Decay products from a nucleus with spin may be distributed non-isotropically with respect to that spin direction, either because of an external influence such as an electromagnetic field, or because the nucleus was produced in a dynamic process that constrained the direction of its spin.

So it was clear that the assumption of a constant, slow decay process was wrong.

There must have been speeded-up decay, perhaps in a huge burst associated with Creation Week and/or a separate burst at the time of the Flood.

Alpha decay is one type of radioactive decay, in which an atomic nucleus emits an alpha particle, and thereby transforms (or "decays") into an atom with a mass number decreased by 4 and atomic number decreased by 2. A radioactive nucleus with zero spin can have no defined orientation, and hence emits the total momentum of its decay products isotropically (all directions and without bias).

However, for a collection of atoms, the collection's expected decay rate is characterized in terms of their measured decay constants or half-lives. The half-lives of radioactive atoms have no known upper limit, spanning a time range of over 55 orders of magnitude, from nearly instantaneous to far longer than the age of the universe.

Certain highly excited short-lived nuclear states can decay through neutron emission, or more rarely, proton emission. random) process at the level of single atoms, in that, according to quantum theory, it is impossible to predict when a particular atom will decay, regardless of how long the atom has existed.

The thing that makes this decay process so valuable for determining the age of an object is that each radioactive isotope decays at its own fixed rate, which is expressed in terms of its half-life.

With the release of key peer-reviewed papers at the 2003 ICC (International Conference on Creationism), it is clear that RATE has made some fantastic progress, with real breakthroughs in this area.
