Production of Radium from Actinium

Abstract

IN a recent letter to this Journal (November 15, 1906) Dr. Boltwood has given an account of experiments which show that radium is continuously produced in a solution of actinium, and concludes that radium is a disintegration product of actinium, the latter occupying an intermediate position in the family of disintegration products between uranium and radium. The radium is produced from the actinium at about the theoretical rate, and he deduces in a simple way that the time for radium to be half transformed is about 3000 years. These results of Dr. Boltwood are of great interest, and mark an important stage in the search for the somewhat elusive parent of radium.
