The elevator device is capable of vertical and rotary motion so that the sample can be scanned both vertically and circumferentially. Typically, active interrogation of a sample takes about 15 minutes. Then it is lowered onto its carrier and the conveyor moves the next sample into position and the process is repeated. At least two persons, a staff member and a technician, are necessary to operate the mobile unit. De- pending on the job requirements, especially if many in-the-field as- says are necessary in addition to in- place interrogations, the staff can be increased. MONAL‘s operation at Rocky Flats is being supervised by Joerg Menzel, of N-6. He is ac- companied by Bert Dennis, a nuclear engineer assigned to the Nu- clear Safeguards program from ENG-6. Technicians Dave Helfer and John Kottman are the laboratory’s operators. Together with other N-6 personnel, they will con- duct precision assay measurements on uranium-235, plutonium-239 Helfer studies the operation of the elevator device as a barrel is lifted into and uranium-238 as MONAL is de- the experimental cavity. ployed at various types af nuclear installations around the United States and perhaps overseas.
