Savannah River Site experimental measurements uncertainty analysis three-beam gamma densitometer system

Technical Report ·
DOI:https://doi.org/10.2172/6908989· OSTI ID:6908989
This report contains the uncertainty analysis on the three-beam gamma densitometers for the Savannah River Site L-Reactor. The densitometer contains a {sup 137}Cs source and radiation detection system,which is mounted on a pipe for making fluid density measurements. The dc voltage output from the densitometer is inversely proportional to the gamma beam attenuation in the fluid, and hence, proportional to the density. The sources of possible errors are discussed for the measurement system and operation. An estimate of the measurement uncertainty for each of the beams on the 16 and 24 in. densitometers is determined. 4 refs., 6 figs., 11 tabs.
