A decade later, American chemist Bertram Boltwood suggested that lead was a disintegration product of uranium and could be used as an internal clock for dating rocks.

By the mid-1940s, Willard Libby realized that the decay of C research—his life’s work—Libby was awarded the Nobel Prize in Chemistry in 1960, and the age of radioactive dating was born.

Considering that the dacite probably erupted in 1986 AD, Austin should have known that at least some of the samples would have given dates that were younger than 2 million years old and that Geochron Laboratories could not have provided reliable answers.

For example, uranium-238 (parent isotope) decays into thorium-234, which itself is unstable, and the process continues until the atom changes into lead-206 (daughter isotope), which is stable.

Considering that the half-life of potassium-40 (40K) is fairly long (1,250 million years, Mc Dougall and Harrison, 1999, p.

9), the K-Ar method cannot be used to date samples that are much younger than 6,000 years old (Dalrymple, 1991, p.

The first assumption is a constant rate of radioactive decay based on uniformity theory—that is, a doctrine which maintains that natural processes have remained constant during earth’s history.

Steve Austin and his associates at the Institute for Creation 'Research' (ICR) collected a dacite sample from Mt. Helens, Washington State, USA, which probably erupted in 1986 AD. then ineffectively separated the sample into several mineral and glass 'fractions', submitted the dacite and its 'fractions' for potassium 40-argon 40 (K-Ar) dating, and subsequently used the bogus results to inappropriately attack the K-Ar method.

Advocates of these methods assume that melting or liquid magma at the beginning resets the age clock to zero (that is, there are no daughter isotopes in the rock at the time of cooling or solidification).

If the rate of decay from uranium to lead is constant (with a half-life of 4,470 million years), and if we know the amount of daughter isotopes in the rock at the beginning, and if we can measure how much parent and daughter isotopes are present in a given rock sample, we can supposedly calculate the age of the rock.

There is no conflict between science and the Bible..one needs is a proper understanding how to merge science and the Bible.

Although the subject of radioisotope dating may seem a bit complicated, the dating method is rather straightforward.

93)Cambridge, Massachusetts, USA, performed the K-Ar dating for Austin et al. However, when they did, their website clearly stated in a footnote that their equipment could not accurately date rocks that are younger than about 2 million years old ("We cannot analyze samples expected to be younger than 2 M.

Y."; also see discussions by advanced equipment, 'memory effects' can be a problem with very young samples (Dalrymple, 1969, p. That is, very tiny amounts of argon contaminants from previous analyses may remain within the equipment, which precludes accurate dates for very young samples.
