Can carbon dating

Hence, it would not be possible to determine the age of a sample accurately.To determine if the result deduced by carbon-14 dating is correct, it is often cross-checked by using other dating techniques like Tree-ring counting, Potassium-40 dating (half-life: 1.3 billion years), Uranium -238 dating (half life: 4.5 billion years), etc.By comparing age of a sample deduced by using carbon-14 dating to results from other dating techniques, discrepancies have been noticed.► With the advancement of nuclear reactors and weapons, it is possible that the amount of carbon-14 has changed in the recent years, specially carbon data from the 1950s and 1960s are questionable.There is also the likelihood of the sample being contaminated with old or new carbon.Would processes like cooling or water circulation have affected its C-14 content?Or take the case of organic remains buried during Noah’s Flood. Secular researchers assume the Flood never happened, so they feel free to apply today’s conditions to the distant past. If a specimen started out with a smaller amount of C-14 than is assumed, its carbon “age” can look older than its real age to those who base their calculations on modern C-14 levels.

What could have caused Ice Age or Flood animals and plants to have less C-14 than modern creatures?

For example, logs of woods cut from different trees were burnt in a fireplace.

The sample of the end result would be contaminated.

The most common form of carbon in the atmosphere is carbon-12, which is a stable isotope of carbon.

An unstable form of carbon isotope, carbon-14, also known as radiocarbon, is formed when cosmic rays hit atoms in the upper atmosphere of the earth.
