Fossil Fuel Emissions Threaten to Reduce Radiocarbon Dating Reliability
• arcleinIt's based on the very simple principle that radioactive isotopes decay at a steady, predictable rate. Radium, for example, has a half-life of about 1,600 years. That is, if you had a solid block of radium, half of it would decay into other elements in 1,600 years. In another 1,600 years, half of that would decay, and so on until it was all gone. If you know how pure your
