An artifact classified as antler, red deer, found in a site at Aveline's Hole, England, is found to have a 14C radioactivity of 5.76×10-2 counts per second per gram of carbon. Living carbon-containing objects have an activity of 0.255 counts per second per gram of carbon. How long ago did the living carbon-containing source for the artifact die? The half-life of 14C is 5730 years.
