Atmospheric C14 is continually produced by cosmic rays in the upper atmosphere. C14 is radioactive and decays into N14 with a half-life of 5,730 years. A sample of charred wood found in the remains of a settlement in Pennsylvania is measured to have a C14/C12 ratio equal to 0.9 e-12 with an accuracy of ±10%. Estimate the age of the wood. What accuracy is required to estimate the age ±25 years? • Show less
