 The uncorrected activity at t=0 can be found to be 521.65 +\- 18.26 Hz. Using the efficiency of Ba-133 at 3.9cm away from the face of detector B, the corrected rate is found to be 30685.29 +\- 1074.12 Hz. Converting this we get 0.83 +\- 0.03 uCi. Now the beam was shut off 140 minutes before the counting began, so tracing that back the initial activity of the sample as it came out of the beam is 4.02 +\- 0.15 uCi.
