Due to the difficulty in getting the activity ratios to match the expected values, I decided to investigate the dead time of the detector in use (Detector A). Below is a table of values used to generate the plot. This will also give the reader a good idea of what the dead times are for certain count rates.
Count Rate (Hz) | % Dead |
129.47 +/- 7.84 | 0.24 +/- 0.10 |
