In 1991, two hikers in the Alps, between Italy and Austria, discovered the remains of a well-preserved mummy that dates back to the Ice Age. The activity of C-14 in the remains of the Iceman was measured to be 0.1220 Bq per gram. In a living organism the rate of radioactive decay of C-14 is 0.2310 Bq per gram. Determine how long ago the Iceman lived. The half-life of C-14 is 5730 years. (in yr) OA: 1732 OB: 2511 OC: 3641 OD: 5280 OE: 7655 OF: 11100 OG: 16095 OH: 23338
Monique, an archaeologist from UWC finds an ancient wooden axe handle at an excavation site at Onderstepoort. She wants to determine the age of the axe handle. She takes a small sample of carbon from the axe handle and places it near a Geiger counter. The counter reads 20 counts/minute. She then takes the same mass of carbon from a living tree and finds that it has a count-rate of 40 counts/minute. a) How old is the axe handle? (assume the half-life of C-14 is about 6000 years) - choose answer below b) Explain your reasoning in 'Rationale'
