The various values for the half lives of Ra and Pa reported in the literature since are given in Table 3.

Because this type of decay involves a particle outside the nucleus, the decay rate may be affected by variations in the electron density near the nucleus of the atom.

Lord Kelvin and the Age of the Earth. One of the primary functions of the dating specialist sometimes called a geochronologist is to select the applicable method for the particular problem to be solved, and to design the experiment in such a way that there will be checks on the reliability of the results. By the mid- to late s the decay constants and branching ratio of 40 K were known to within a few percent from direct laboratory counting experiments 2.

The radii of these rings are proportional to the energies of the particles. Some of these data were later compiled in the book by Faul 46 that Cook 28 cites as the source of his data. Bishop James Ussher, a 17th-century Irish cleric, for example, calculated that creation occurred in B. The K-Ar method has two principal requirements.

This chord is called discordia. There is far too much Ar 40 in the earth for more than a small fraction of it to have been formed by radioactive decay of K The differences in the reported half lives are a consequence of improved methods and instruments, and the care with which the individual measurements were made.

A Response to “Scientific” Creationism

Although this technique looks good at first, carbon dating rests on at least two simple assumptions. The U-Pb concordia-discordia method circumvents the problem of lead loss in discordant systems and provides an internal check on reliability.

Note that this method is not only self-checking, but it also works on open systems. Neutron reactions do not change decay rates but, instead, transmute one nuclide into another. Because these types of radioactive decay occur spontaneously in the nucleus of an atom, the decay rates are essentially unaffected by physical or chemical conditions.
