Report describing the use of a 5" x 3" NaI(Tl) detector and a high pressure ionization chamber to obtain gamma ray spectra and total gamma dose rates at approximately 100 locations during the course of several survey trips in the southeastern, central, and western United States. Reasonably precise elements of the dose rates are made using the pulse height spectra and relatively simple methods of analysis. Total terrestrial dose rates as well as the partial dose rates from the uranium-238 series, thorium-232 series, potassium-40, zirconium-niobium-95, and rhodium-106 are tabulated for each location.
