6) The useful range for carbon dating is between 100 and 30,000 years. 7) Potassium-40 has a half-life of 1.3 billion years and decays to argon-40.
a) How long will it take for 20 grams of potassium-40 to decay to 5 grams?
Once the plant or animal dies the carbon-14 decays to nitrogen-14 at a steady rate.
The longer an organism is dead the lower the carbon-14 content. An archeologist extracts a gram of carbon from an ancient bone and measures the emitted radioactivity at between 15 to 16 beta emissions per minute. A one gram carbon sample was obtained and beta emissions recorded.
The technique is also potentially capable of providing the year of birth and/or death of an individual.
