Inspection Summary
The inspection consisted of:
• Observing radiological postings around the Mill;
• Observing Mill personnel perform exit surveys:
• Reviewing documentation of:
o Weekly Alpha surveys;
o Monthly Gamma surveys; and
• Taking dose rate and contamination measurements around the Mill.
The following discussion provides more detail of each inspection items.
Item 1. Radiological Postings:
Observations: During the Mill Tour the inspector observed the following posted areas:

Lunchroom No Posting 35 pR/hr
Lunchroom #2 No Posting 25 µR/hr
Note: Due to no uranium production at the time of the inspection there are fewer posted areas in the Mill.
The Inspector also collected large area swipe samples in six areas within the restricted area.

Item 2. Exit Surveys: The Inspector observed employees survey themselves out of the restricted area and
checked the alpha metersused.
Observations: The Mill uses Alpha scintillators for exit surveys. The Inspector checked the settings of the
survey instruments and found that they were set properly. Meters are calibrated annually. The Mill
personnel that were observed performing exit surveys, did the surveys appropriately. The Mill's RSTs also
perform random checks on exit surveys.

Deficiencies: None
Item 3. Radiological Surveys and Monitoring: The Inspector reviewed the weekly surveys done around
the Mill.
Observations: The Inspector reviewed the radiological monitoring documentation performed at the Mill
site. The documentation indicated that:
• All areas of the Mill are being survey for radiological conditions;
• Surveys indicate that the Mill is being maintained within regulatory radiological parameters
• Documentation is legible, complete and using appropriate units; and
• "Clean" areas are being maintained.
The Inspector also looked at dosimeter usage. The inspector observed:
• Mill personnel were properly wearing their dosimeters on the torso of the their bodies;
• Dosimetery was being properly stored in the locker room and administration building; and
• Each employee is assigned a dosimeter.
