Abstract
A method is described for measuring the radium content of substances in which the radium concentration is of the order of micrograms per gram of material. The gamma-ray activities of the unknown material and of a standard radium capsule are compared by means of Geiger-Müller counters. Corrections for self-absorption and distance are given for rectangular and cylindrical sources. The effect of radiation scattered by the source into the detector is discussed. Synthetic bulk sources made up with known quantities of radium were used for the experimental work.
