Abstract
THE half-life period of radioelements formed when metallic zinc, caesium nitrate, thallium acetate and bismuth carbonate are submitted to bombardment by slow neutrons is given by Prof. J. C. McLennan, Mr. L. G. Grimmett and Mr. J. Read. The authors also describe a way of plotting the observed activity, which allows of a more exact determination of the life period of relatively long-lived radioelements.
