EXPLORATION OF RADIOMETRIC METHODS FOR INDUSTRIAL PROCESS CONTROL. Final Report

Technical Report ·
OSTI ID:4059773
A survey was conducted of various beta emitting isotopes that may have possible application in a radiometric analysis. Approximately one-third of the elements of the periodic table can be determined, using this technique. Experimental work was carried out on the determination of the following ions: chloride, bromide, iodide, chromate, and cyanide ions using silver-110; chloride using mercury-203; barium and lead using suilur-35; fluoride using calcium-45; zinc and manganese using phosphorus-32. A variation of the radiometric equation can be applied for the determination of nickel using nickel-63 and for sulfate using sulfur-35. The radiometric analysis principle was applied to the development of a centrifuge-counter to perform the analyses semiautomatically or automatically. It consists of a spinning cylinder within which there is a stationary thin-walled beta detector. The precipitation reaction is carried out and the slurry is applied to the inside wall of the spinning cylinder. The solid precipitate migrates to the wall where it is covered by a layer of solution sufficiently thick to shield the detector from the radioactivity of the precipitate. The resulting count rate will largely represent that of the supernatant solution only. Present development of the centrifugs counter is limited to the semi-automatic stage. (auth)
