SUBJECT:
LETTER REPORT FOR ANALYTICAL RESULTS FOR EIGHT SOIL SAMPLES AND ONE WATER SAMPLE FROM NASA PLUM BROOK, SANDUSKY, OHIO
[INSPECTION REPORT NOS. 05000030/2012-001; 05000185/2012-001]

Dear Mr. Tapp:
The Oak Ridge Institute for Science and Education (aRISE) received eight soil samples and one water sample on October 24, 2011 from NASA Plum Brook in Sandusky, Ohio. The samples were analyzed according to the NRC 303 form supplied with the samples. The sample identification numbers are presented in Table 1. The gamma spectroscopy results for cobalt-60 and cesium-137 are presented in Table 2. Strontium-90 and tritium results are presented in Tables 3 and 4, respectively. The pertinent procedure references are included with the data tables.
aRISE's Quality Control (QC) requirements were met for these analyses. The QC files are available for your review upon request.
My contact information is listed below. You may also contact Dale Condra at 865.241.3242 with any questions or comments.
Sincerely,
