Radiochemical Separation and Measurement of Induced Activities. Standard radiochemical procedures (3, 6, 9) were employed and the final precipitate was counted for beta activity on counting equipment which had been previously calibrated with standard beta emitters. This calibration took into consideration coincidence losses, energy dependence, and the counting geometry; this made it possible to convert the raw count rate into disintegrations per second.
