Donald Thompson:

The answer to your question is probably in the SSD registry, http://www.hsrd.ornl.gov/nrc/sources/index.cfm .

Our local RSO has a question about the activity of a Ba-133 calibration source in an old Packard TopCount NXT liquid scintillation counter. He has no literature on the unit, will be moving it to a new facility and doesn't want to dismantle the unit, then find no label on the source. Can anyone help him?
