Accuracy of radioactive dating
It is assumed that we are dealing with a closed system—no loss of either parent or daughter elements has occurred since the study material formed.
No scientist can guarantee that any sample can be considered a closed system unless it was isolated from its environment when it was formed.
Radiometric dating techniques are thus based on sound scientific principles, but rely on so many basic assumptions that Bible believers need not have their faith shattered by data derived from these techniques.
The latest high-tech equipment permits reliable results to be obtained even with microscopic samples.For more on this subject, see the video Bones in Stones i. Ogden III, "Annals of the New York Academy of Science," 288 (1977): 167-173. In a related article on geologic ages (Ages), we presented a chart with the various geologic eras and their ages.While there is no proof that the rates were different in the past than they are today, there is also no proof that they were the same.Thus radioactive dating relies purely on assumptions.
