OSTI ID:4184710
An investigation was made of various factors which influence the efficiency of linear type Kr/sup 85/ static eliminator units. Among the variables examined were source tube material, Kr/sup 85/ content, housing configuration, distance of source from charged surface, plus area and potential of charged surface. Based on the experimental results, a prototype Kr/sup 85/ static eliminator unit was designed, fabricated, and tested. The essential design features are described. The relative ionizing efficiencies of encapsulated Kr/sup 85/ gas and Ra/sup 226/ foil were determined. Under the experimental conditions employed, it was found that 350 mc Kr/sup 85/, encapsulated in 0.0035 in. wall aluminum alloy tubing, produces ionization approximately equivalent to that for a 1 mc Ra/sup 226/ foil. This relationship applies when the Kr/sup 85/ source tube is mounted in the prototype housing and the Ra/sup 226/ foil in a commercially available housing. Radiation profiles were determined for a number of sources. The effect of various exterior shielding on radiation profiles is illustrated. (See also AECU-4363.) (auth)
