Rdiometric dating

07 Mar

[Any atom found in nature with a shorter half-life, such as carbon-14 or radon, is being produced by on-going nuclear reactions.] The 450 million-year value is significant because it is one tenth the estimated age of the solar system.After ten half-lives the number of parent atoms decreases by a factor of about a thousand, and it is generally accepted that the number of parent atoms remaining in nature would be negligible.– Perhaps it is mainly concordant dates that get published and discordant dates are ignored.Occasionally however, even discordant dates can be found in the literature.(a) The strong force that governs nuclear decay rates is several orders of magnitude greater than the electromagnetic force that governs atomic interactions at even the highest temperatures and pressures found on earth.

Using the current understanding of radiometric dating, it is difficult to fit the data into a one-year flood a few thousand years ago; however, creationists have given a number of responses that are here divided into eight categories: (1) The radiometric age data is bad.Seventh-day Adventists show their great interest in time by having it as part of their name, referring to a recent seven-day creation in the past and a soon-coming advent of Christ in the future.Within this philosophical and theological context of time, the next sections discuss geological time as determined by radiometric dating: (1) how the technique works well and (2) some young-earth creationist responses.The resulting ages are based on several assumptions: (a) the decay rate has been constant; (b) the original number of parent and daughter atoms in a sample can be estimated; and (c) the system [bone, wood, mineral, rock, etc] has not lost or gained parent or daughter atoms after the time of the event being dated, except by radioactive decay.In many cases these assumptions seem to be valid, and when they are not it is often obvious.
