Calibration of a Neutron-Driven Gamma-Ray Source

Source

Cadmium and iron cylinders in the thermal-column cavity of the National Bureau of Standards Reactor (NBSR) provide intense sources of neutron capture gamma rays. The strength of the gamma-ray fields have been calculated from measurements of the neutron interaction rates in the cadmium and in the iron cylinders. The neutron interaction rates were measured by activation foils fixed on the surface of the cylinders and by direct counting of the activated cylinders. Miniature fission chambers have been used to measure the axial distributions.
