What is carbon-14 dating?
A fossil is found that contains 6.25% as much Radium-226 as fossils being formed today.
The half-life of Radium -226 is 1.60 x103 years. How old is the fossil?
Hint: How many half-lives did the Radium-226 go through for 6.25% to remain?
So, how many years have passed over 4 half lives?
Uranium-lead (U-Pb) dating of geological samples is one of the oldest and most refined radiometric dating methods, able to determine ages of about 1 million years to over 4.5 billion years with precision in the 0.1–1% range. The U-Pb dating method relies on two separate decay chains, one of which is the actinium series from 235U to 207Pb, with a half-life of 704 million years.
Geologists unearth a sample of zircon that appears to be a closed system. They find 0.714 grams of 207Pb for 1.000 grams of 235U present. Approximately how old is the sample?
