Separation of Polonium from Bismuth by Distillation.

摘要

The experimental work on the separation of polonium from bismuth by distillation during the period from 1949 to 1952 is reviewed. Data are presented showing operation of simple batch stills and of fractionating stills with and without helium sparging. The problem of materials of construction is discussed and data obtained while working on this phase of the project are included. Some of the problems of still design and construction are presented with recommendations for their solution. jg p.5.
