The spatial distributions of indium resonance neutrons about a ``point'' Ra‐Be source have been measured in pure CaCO3(limestone) and SiO2(sand) out tor2≈9&tgr;. Both media show nearly Gaussian distributions corresponding to Fermi ages &tgr;(SiO2)=1906±90 cm2and &tgr;(CaCO3)=461±23 cm2over most of the range observed. Excess resonance flux near the source, more pronounced in CaCO3than in SiO2, appears to be due to inelastic scattering although such interpretation is not unambiguous. Space integrals indicate ∼10 percent more absorption in CaCO3than in SiO2during moderation. Data were corrected for 4.5‐hr activity, 54‐min activation by high energy neutrons, and edge effects; consideration was given to the 3.9‐ and 9‐ev In levels in defining the mean detection energy and to the nonmonoenergetic nature of the Ra‐Be source in affecting the shape of the indium resonance spatial distribution.
