Gamma spectra of the 234, 235, and 238 uranium isotopes. [Tables, curves]

Description: Eight sources of uranium of varying /sup 235/U enrichment were used to collect detailed ..gamma..-ray spectra with a GeLi detector over the energy range from 50 to 250 keV. The characteristic x rays of thorium and uranium were identified. Included in the spectra were ..gamma.. rays present in the decay of the 234, 235, and 238 uranium isotopes. The efficiency of the detector was determined and used to calculate both conversion coefficients for the /sup 234/U decay ..gamma.. rays and the abundan… more

Feasibility study for use of a germanium detector in the LOFT gamma-ray densitometer

Description: The primary aim of this study is to predict the performance of a gamma-ray densitometer system using computer modeling techniques. The system consists of a collimated /sup 137/Cs source, a pipe containing a variable amount of water absorber, and a shielded and collimated germanium detector system. The gamma-ray energy spectrum (number of photon counts as a function of energy) has been computed for several sources at the detector. The response for combined sourceconfigurations has been obtained … more

Atomic absorption instrument functional description

Description: This report describes a proposed system for automating atomic absorption analysis. The system consists of two atomic absorption instruments and an automatic sampler that can be attached to either instrument. A computer program controls the sampling and gathers data. The program then uses the data to perform bookkeeping, data processing, and report writing.
