A half-curie Co/sup 60/ source was calibrated by total absorption adiabatic calorimetry. The mean value of the source activity measured calorimetrically was 1.73% less than the value obtained by the United States Bureau of Standards by coincidence measurements. Apparatus is described which maintained adiabatic control between the bath and calorimeter within plus or minus 0.0003 deg C. (auth)
