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 |
| 154.33 +/- 10.36 | 0.29 +/- 0.11 |
| 194.83 +/- 8.36 | 0.41 +/- 0.11 |
| 253.69 +/- 14.05 | 0.51 +/- 0.18 |
| 257.11 +/- 11.24 | 0.53 +/- 0.14 |
