HALF LIE RADIOMETRIC

22 These and other examples raise a critical question half lie radiometric. From there, we can begin to calculate the age of the earth. This can be done by chemical means, but for precise determinations, mass spectrometry can be used half lie radiometric. In 1913, Arthur HolmesÃ¢Â€Â™s book, The Age of the Earth, gave an age of 1. This does not mean that a 14C date of 50,000 or 100,000 would be entirely trustworthy.
As long as an organism is alive, it takes in 14C and 14C is radioactive (decays into 14N), the amount of 14C in a dead organism gets less and less over time. They require very careful study of more than one passage. 17 The current accepted age of the earth is about 4. Now suppose that there was an original amount of the daughter element present at the formation time of the sample being studied. Andrew Snelling, a geologist, points out several of these problems with potassium-argon, as seen in table 7.
