An Improved Method for the Determination of the Radium Content of Rocks
<p>A modified form, developed in this laboratory, of the furnace method for separating radium emanation from rocks originally devised by J. Joly, is described. In the new method the rock is heated with a flux in a nickel crucible by means of a gas flame, the carbon dioxide produced is removed...
