Description

As reported in the previous Progress Report (December 16, 1959) a stock solution of Th 230 was prepared from pitchblende. Pulse height analysis of this solution indicated the presence of only Th 230 (93%), Th 227 (5%), Th 232 (1%), and Th 228 (1%). This solution was used to make up synthetic thorium solution of various concentration. These synthetic solutions were analyzed to establish a chemical yield for the procedure. Neither the precision nor the chemical yield of the procedure were considered to be satisfactory. In the next report period, we hope to complete the testing of the thorium procedure, … continued below

Neither the precision nor the chemical yield of the procedure were considered to be satisfactory. In the next report period, we hope to complete the testing of the thorium procedure, both with regard to chemical yield and precision, as well as to determine decontamination factor from radium, uranium, and polonium. To do this, pure solutions of polonium, radium, and uranium will be prepared. The polonium and radium will be processed from pitchblende while the uranium will be made by purifying reagent grade uranyl nitrate.
