Question: A radiation counter is to be calibrated using a 1 - Ci 5 4 Mn gamma - ray source ( E = 0 . 8

A radiation counter is to be calibrated using a 1-Ci 54Mn gamma-ray source (E =0.835 MeV). The counter registers 2,120 counts in 600 seconds when no sample is present and 24,632 counts in 60 seconds when the standard 1-Ci source is present. (a) What is the background count rate and its uncertainty? Answer: (b) What is the gross count rate and its uncertainty? Answer: (c) What is the net count rate and its uncertainty? Answer: (d) What is the efficiency and its uncertainty?
