Plutonium Plant Building Dose Rate Survey On October 11,1989, a dose rate survey was made in the Plutonium plant building using a low energy Bicron p Rem instrument (serial No.
A 905N) equipped with an extended detector.
The instrument was calibrated by Bicron Corporation on September 24,
- 1989, and the calibration was rechecked by Ron Fine, Cimarron, on October 3, 1989.
The dose rate measurements were taken one meter above the floor. From one to four measurements were taken in each room or area, depending upon the size of the room or area.

Plutonium Plant Yard Dose Rate Survey On October 4, 1989 a dose rate survey was made in the plutonium plant yard using a low energy Bicron Rem instrument (serial No.
A 905 N) equipped with an extended detector.
The instrument was calibrated by Bicron Corporation on September 25,
- 1989, and the calibration was rechecked by Ron Fine on October 3, 1989.
The dose rate measurements were taken one meter above ground level on ten meter grid.
Additional readings were taken at the sides of the building and at the fence lines which were not on ten meter grid points.
A copy of the grid map is attached.
