Radiometric dating of human fossils
Outside the range of recorded history, calibration of the 14 clock is not possible.This means the above calculations are only evolution speculation and NOT backed up by real science.This element is locked in tiny zircons within the granite. While it stays within the zircon for a period of time, being a very small atom, helium escapes the zircon within a few thousand years.When creation scientists studied granite samples, they made interesting discoveries.
If we knew the amount of carbon-14 in an organism when it died, we could attempt to date the time of death.The key questions then are: Has the atmospheric ratio of carbon-14 to carbon-12 changed in the past, and if so, why and how much?The assumption usually made, but rarely acknowledged, is that the ratio of carbon-14 to carbon-12 in the atmosphere before the industrial revolution has always been the sameabout one in a trillion.However, before accepting any radiocarbon date, one should know how the technique works, its limitations, and its assumptions.One limitation is that the radiocarbon technique dates only material that was once part of an animal or plant, such as bones, flesh, or wood. To understand the other capabilities and limitations of radiocarbon dating, we must understand how it works and consider the flood. However, roughly one in a trillion carbon atoms weighs 14 atomic units. It is also called radio carbon because it is radio active (but not dangerous).
