THE METHOD OF DETERMINING THE ISTOPIC COMPOSITION OF URANIUM WHICH COMPRISES FORMING AN AQUEOUS ELECTROPLATING SOLUTION CONTAINING A WEIGHED AMOUNT OF THE URANIUM TO BE ANALYZED AND 0.04 TO 40 MILLIMOLES OF AN AMMONIUM SALT OF A WEEK ACID, ELECTRODEPOSITING THE URANIUM IN SAID SOLUTION ON ONE FLAT SURFACE OF A CATHODE BY PASSING THROUGH SAID SOLUTION A CURRENT IN THE RANGE OF 0.04 TO 0.16 AMPERE PER SQUARE CENTIMETER OF CATHODE SURFACE MEANWHILE MAINTAINING SAID SOLUTION UNDER AGITATION AND AT A TEMPERATURE BETWEEN 45* C. AND 95* C. UNTIL SUBSTANTIALLY ALL OF THE URANIUM IN SAID SOLUTION HAS BEEN DEPOSITED ON SAID CATHODE, SAID CATHODE PROVIDING AT LEAST 1 SQUARE CENTIMETER OF SURFACE FOR DEPOSITION PER MILLIGRAM OF URANIUM IN SAID SOLUTION, AND MEASURING THE INTENSITY OF RADIATION EMITTED BY THE LAYER SO DEPOSITED TO PERMIT CALCULATION OF THE ISOTOPIC COMPOSITION FROM THE MEASUREMENT OF RADIATION INTENSITY AND THE WEIGHT OF THE URANIUM IN SAID SOLUTION BY COMPARISON WITH A STANDARD.
