Mobileflirt4 - Reliability of radiometric dating

Even looking at geology alone, it is evident from the using a young earth. And, although you can come up with gross errors using radiometric dating, by and large, the millions of dates that have been accomplished lend support to their accuracy, granting, of course, a large margin of error.

These "millions" of semi-accurate dates have correlated throughout the stratigraphic layers of the earth. Are they usable for giving a rough estimate of age..

By measuring the ratio of the radio isotope to non-radioactive carbon, the amount of carbon-14 decay can be worked out, thereby giving an age for the specimen in question.

But that assumes that the amount of carbon-14 in the atmosphere was constant — any variation would speed up or slow down the clock.

For example, a team at Purdue University in Indiana was monitoring a lump of manganese-54 in a radiation detector box to measure the isotope’s half-life.
