Due to decay rates of isotopes, carbon dating is good to about 50,00 years, then is limited by the precision of analytical techniques used to find the different isotopes. For older materials, you'll need another isotope. 238U decays to 206Pb with a half life ~4.6 billion years. But, in order t...
Where can I find a tab of this? I've seen tabs for the cream version, but I can't quite figure out some of the little differences.
