Duke Energy would like to know the following:
Source isotope(s) used for calibration of:

1.     Portal Monitors (Cs-137)

2.     Personnel Contamination Monitors (Tc99)

3.     Tool Monitors (SAMs) (Cs-137)

Source isotope(s) used for daily/weekly source checks of: (same radionuclides 
used for calibration)

1.     Portal Monitors

2.     Personnel Contamination Monitors

3.     Tool Monitors (SAMs)

I am sure these have been asked before, if anyone has a current table of 
responses you can forward them directly to me,  otherwise I will tabulate the 
results and distribute.
