Radiocarbon dating questions:
(a) Outline how scientists are able to use radioactive carbon-14 to find the age of fossilised organic material.
(b) A sample of 1 g of a growing oak tree produces a corrected count of 144 in 10 minutes.
(i) What uncertainty is there in this corrected count?
(ii) The half-life of 614C is 5700 years. How old would a fossilised piece of oak tree be if its corrected count in 10 minutes was 18?
(c) Scientists used radiocarbon dating to determine the amount of 614C in a historic artefact. They found it was 92% of that in living tissue. How old is the artefact?
