Carrie, These events you describe do not rise to the level of PCEs in our system procedures. They would require identification of the material and if enough of them were evident we would do a trend report to analyze them as a trend.
We use the EPRI guidance for establishing our PCE limits.

The follow up count for dosimetry purposes shows up clean, indicating the contamination was most likely surface contamination on the individual's clothing etc. Bruce Power is asking whether your plant: - considers these events as Personnel Contamination Events in your metrics - does any follow up to determine the cause of the contamination event, and if so to what extent?
