Calibration of a source

["Peter Skeels" <pskeels@REHS.rutgers.edu>]

Dear Radsafers,

	I am interested in finding a company who can come to our university 
and calculate an activity of our Co-60 source.  I am told that years 
ago the Army donated the source to the university and at that time 
the activity was known.  Unfortunately, that time is gone and no one 
knows what the activity is now.  We need to use the source for 
calibrations, so the activity needs to be accurate.  At one time I 
had heard that J.L Sheppard and Co. did this type of work, but I 
don't have their number.  If anyone has any info for them or any 
other company for this type of work, please let me know.  I thank 
everyone in advance.
