PublicĀ baseline results are presented in the following table. To maintain confidentiality, no individual results are presented. To interpret the monitoring results, one should compare the percentage of results greater than adecision level (LC) for the operational monitoring counts to the same percentage for the baseline counts. If the operational monitoring percentage is statistically greater than the baseline percentage, this suggests that a particular radionuclide may now be present (or present at a greater frequency) in the local population. The percentage of results greater than LC for operational monitoring would be considered statistically different from the baseline percentage ifthe baseline percentage is not contained within the margin of error for the operational monitoring percentage
Count Results as of June 1, 2003
Radionuclide | In Vivo Count Type | Baseline Counts (prior to 3/27/99) n = 367 |
Public Monitoring Counts (3/27/99 through 6/1/03) n = 508 |
