WebAnswer: Very simply. Radiocarbon dating doesn't work well on objects much older than twenty thousand years, because such objects have so little C-14 left that their beta radiation is swamped out by the background radiation of cosmic rays and potassium-40 (K-40) decay. Younger objects can easily be dated, because they still emit plenty of beta ... Weba break-through in our attempts to accurately date the earth came when. radioactivity was discovered.
