The results obtained by Ramsay and Cameron on dissolving radium emanation in water and in copper sulphate solution have made it advisable to investigate the behaviour of the emanation, when dissolved in such solvents, from a radio-active standpoint. There are two possible explanations for the results obtained by these authors:— (1) The one advanced by them to the effect that theα -particle is not identical with the helium atom, but that the “degradation” of the large molecule of the emanation is effected by bombardment withα -particles, the products of the degradation varying according to whether, on the one hand, the emanation is alone or mixed with other gases, or, on the other, whether it is dissolved in water or copper sulphate solution.
