New Precision Technique for Removing Radioactive Emanations From Matter, and for Measuring Minute Quantities of Radon and Thoron
<p>I. INTRODUCTION: The accurate determination of the radium content of ordinary matter has many applications in cosmology and geophysics, but is a difficult analysis to carry out. Two problems are involved, first the removal of radon from the material being tested, then the accurate measurem...
