SUBJECT:

ANALYTICAL RESULTS FOR SIX SOIL SAMPLES, BATCHES O N E AND TWO, FROM BIG ROCK POINT NUCLEAR STATION, CHARLEVOIX, MICHIGAN [INSPECTION REPORT N O . 050-00155/2006-0011 (RFTA N O .06-001)

Dear Mr. Snell:

The Oak Ridge Institute for Science and Education (ORISE) receivedBatch One on July 7,2006, consisting of three sollsamples, and Batch Two on July 26, 2006, consistingof three soil samples thatarc associated with the Big Rock Point Nuclear Station in Charlevoix, Michigan. The six soil samples were analyzed by gamma spectroscopy (GS). Sample identification and collection data are presented in 'l'ablc 1 . The primary isotopes of concern were cobak60 and cesium-137. The GS data are presented in Table

2. The pertinent procedure references areprovided in the specific tables.

ORISKs Quality Control (QC) reqnirements were met for tlis analysis. The QC files are avahble for your review upon request.

My contact information is listed below. You may also contact Wade Ivey at 865.576.9184with any questions or comments.
