The diffraction of light by a U.S. penny and an aperture of the same size with the light source and viewing screen 20 m from the objects has been investigated quantitatively. It was found that the diffraction by these relatively large objects involving such unusually long light paths could be adequately described by the scalar theory of Kirchhoff in the specialized form due to Lommel. Differences noted between the theory and the measurements are discussed, with probable causes indicated.

This report summarizes and evaluates field tests of the Active Well Coincidence Counter (AWCC) at Winfrith and Dounreay, United Kingdom. The applicability of the AWCC for assaying the uranium content of a wide variety of materials was demonstrated and calibration curves were generated. The AWCC was used in three modes (fastj thermal, and passive) while assaying powders, pellets, cartridges, plates, assorted residues, and materials-testing-reactor fuel assemblies.
