The direct determination of 238U in various soil samples was done by measuring the 63.3-keV transition from the decay of the first daughter 234Th. Potential errors resulting from the chemical non-equilibrium of 238U with its daughters are thus avoide

The Lawrence Livermore Laboratory continuously monitors the levels of radioactivity within the Livermore Valley and Site 300. Results of analyses perfomned during 1973 for gross radioactivity and for specific radionuclides of interest in a variety of
