Carroll, J G; Bolt, R O

Simple calorimeters were built comprising an insulated lead rod so constructed that heat flowed in one direction. Heat induced in the lead by gamma rays caused heat to flow, producing a temperature gradient which was used as an index of gatruna dose rate. The calorimeters were calibrated using accepted standards in the Canal Gamma Source at the Materials Testing Reactor. Calorimeters were then exposed in Hole E-5 of the Brookhaven Graphite Reactor while the reactor was operating at 25 megawatts on natural uranium. Gamma flux at the reactor center line was found to be 10/sup 12/ photons/cm/sup 2//sec. (auth)
