Abstract

This report describes the use of five electroscopes used as national standards for radioactivity for the United States during the early 20th century. This set of instruments were used for the calibration of thousands of radium-226 sources used in medical therapy in the US from 1913 to 1989. The provenance of these instruments is recorded here to aid historians and curators in preservation of knowledge and artifacts of early radioactivity measurements in the United States.
