We count all cases equal to or greater than 100 ccpm, not just greater than 100 ccpm. This is consistent with the EPRI report, and it makes a significant different because many cases are recorded as 100 ccpm.

Reply from Browns Ferry I would like to know how PCE's are classified at your plants? i.e. Is contamination on any type of clothing/coverall counted as a PCE? Classified using EPRI guidance with the readings on the outside of the clothing Is contamination on scrubs counted as a PCE? Yes Are all instances tracked and recorded as a PCE? All greater than 100 cpm with a frisker What instances of contamination on a person or clothing would not qualify as a PCE? Due to Radon progeny, medical isotopes or Nobel gas The different interpretations of the EPRI guidance and how it is applied is one of the challenges of benchmarking. It is hard to make a comparison without knowing how the EPRI guidance is applied. Chuck Creamer Charles E. Creamer Health Physicist Tennessee Valley Authority Browns Ferry Nuclear Plant P.O.
