| Abstract |
A detailed account is given of the construction, operation, and characteristics of an emanation system for the determination of radium-226. The method is specific for radium-226, is well suited for large volume samples containing small quantities of this nuclide, and will accommodate any type of sample that can be prepared in an aqueous solution. The limit of detection at the 95-percent confidence level was calculated to be 0.016 picograms of radium-226, and the transfer and collection of radon-222 was determined to be 100 percent with an average deviation of 3 percent.
