Answer to Question #92924 in Atomic and Nuclear Physics for Sarah Snyder

Question

Radiocarbon dating is the methanol method allows science to estimate the age of an organism after they died. fairly consistent amount of radioactive seeds 14 remains in the animal life what does the sea 14° overtime see 12 by measuring the amount of these two and a dead organism compared to living on along with the knowledge of half-life of C4 is 5730 years.
Can you determine how long the organism died?

Answer 1

We have:

$$N=N_0 2^{-t/T}$$

$$12=14\cdot2^{-t/5730}$$

$$t=1274\ years$$
