A small piece of papyrus is to be 14C dated by a 10 minute run of the detector set to record 14C decays, 1500 counts were recorded. With the detector set to transmit 12C3 ion decay products in an ion beam, the ion current is 12μA. a) Compute the 14C/12C are transmitted with the same efficiency. b) If the entire 14C sample is consumed in 75 minutes, what was the mass of the 12C it contained (assume a constant consumption rated and an efficiency of 0.015). c) How old was the sample?

Question
A small piece of papyrus is to be 14C dated by a 10 minute run of the detector set to record 14C decays, 1500 counts were recorded. With the detector set to transmit 12C³ ion decay products in an ion beam, the ion current is 12µA. a) Compute the 14C/1?C are transmitted with the same efficiency. b) If the entire 14C sample is consumed in 75 minutes, what was the mass of the 12C it contained (assume a constant consumption rated and an efficiency of 0.015). c) How old was the sample?
