Radiocarbon dating is effective on specimens up to 40,000 years old. In 1951, a nuclear chemist was trying to determine the age of some scrolls that were recently found. Carbon-14 has a half-life of 5730 years. If he found 79.3 % of the original carbon-14 still present, in about what year were the scrolls made?
