Re: Calibration of a source

Peter,  

Call your Radiation Therapy department and ask to talk to a Physicist.  All
Rad Therapy accelerator calibrations are based on chambers with NIST(National
Institute of Standards and Technology, formerly NBS) traceable calibrations
from an accredited laboratory.  The Medical Physicist will have such a chamber
and will be able to take an exposure measurement which can be use to calculate
the Co-60 source activity.
