The article discusses the analysis of radiocarbon from nuclear bombs tests in the early 1960s in criminal forensics investigations. Topics include a radioisotope of carbon commonly used in forensics, called carbon-14, missing persons research by archaeologist Fiona Petchey at Waikato University in New Zealand using carbon-14 dating, a sharp rise and fall of atmospheric carbon, called the bomb curve, and the bomb curve's use to prevent poaching.
