On pages and of The Genesis Flood, creationist authors Whitcomb and Morris present an argument to try to convince the reader that ages of mineral specimens determined by radioactivity measurements are much greater than the "true" i. Radiometric dating is a widely accepted technique that measures the rate of decay of naturally occurring elements that have been incorporated into rocks and fossils. This makes radiometric dating quite reliable. The dates produced have gotten steadily more precise as lab techniques and instrumentation has been improved. Well, we know this because samples of his bones and hair and even his grass boots and leather belongings were subjected to radiocarbon dating.

Radiocarbon dating

Other events on earth can be dated equally well given the right minerals. This scheme is used to date old igneous and metamorphic rocksand has also been used to date lunar samples. This scheme has been refined to the point that the error margin in dates of rocks can be as low as less than two million years in two-and-a-half billion years. Simply stated, radiometric dating is a way of determining the age of a sample of material using the decay rates of radio-active nuclides to provide a 'clock. In uranium—lead datingthe concordia diagram is used which also decreases the problem of nuclide loss. The development of radiocarbon dating has had a profound impact on archaeology. Morris makes a number of unsupported assumptions:
