RESULTS FOR SIX SOIL SAMPLES, BATCHES ONE AND TWO, FROM BIG ROCK POINT NUCLEAR STATION, CHARLEVOIX, MICHIGAN [INSPECTION

REPORT NO. 050-00155/2006-0011 (RFTA NO.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.
