Carbon-14 dating is useful for estimating the age of samples generally no older than about 50,000 years. The older the object, the harder it is to accurately determine the age. Other techniques must be used to estimate ages much greater than 50,000 years. Living organisms (and materials made of recently deceased living organisms) contain a large amount of Carbon-14. After the organism dies, its Carbon-14 slowly decays. Carbon-14 has a half-life of 5730 years. **Estimate** the age of an object with a carbon-14 activity of 4.61% of a current living organism.Think about how you could make a reasonable quick estimation using what you know about half-life.

Question
Transcribed Image Text:Carbon-14 dating is useful for
estimating the age of samples
generally no older than about 50,000
years. The older the object, the harder
it is to accurately determine the age.
Other techniques must be used to
estimate ages much greater than
50,000 years. Living organisms (and
materials made of recently deceased
living organisms) contain a large
amount of Carbon-14. After the
organism dies, its Carbon-14 slowly
decays.
Carbon-14 has a half-life of 5730 years.
**Estimate** the age of an object with
a carbon-14 activity of 4.61% of a
current living organism.Think about
how you could make a reasonable
quick estimation using what you know
about half-life.
