Fill in blanks below with the missing information:
Scientists can determine the age of ancient objects by a method called radiocarbondating. The bombardment of the upper atmosphere by cosmic rays converts bitrogen toa radioactive isotope of carbon, C-14, with a half-life of about 5730 years. Vegetationabsorbs carbon dioxide through the atmosphere and animal life assimilates C-14 throughfood chains. When a plant or animal dies it stops replacing its carbon and the amount ofC-14 begins to decrease through radioactive decay. Therefore, the level of radioactivitymust also exponentially decay. A parchment fragment was discovered that had about74% as much C-14 radioactivity as does plant material on the earth today. Estimate theage of the parchment.
