Radium Production in United States.

C. H. Viol, writing in Science, states that the total production of radium element in the United States down to 1919 is about 55 grams, which Is probably more than half the total radium produced in the world. During the war, with no carnotite exports, the greatest part of the world s radium supply has been produced in this country. In 1918 the United States produced 13.6 grams. With regard to a discussion that has occurred concerning the amount of Vadium that can be produced from the carnotite fields, Mr. Viol says that the carnotite holdings of the Standard Chemical company, which comprise about 35C claims and are the largest holdings under the control of a single concern, are estimated to be capable of yielding aV least 500 grams of radium.— Scientific American.
