Extract

(1) A method has been devised and applied for measuring the decay Constant of radium emanation, the method depending on careful comparisons with a simple electroscope under the most favourable conditions.

(2) A mean value for the Constant of radium emanation has been obtained, with an error unlikely to exceed 0·2 per cent.: λ = 0·1808 day−1, or half-period 3·833 days.
