Excerpt from The Radioactivity of Lead From these observations it would appear that the rise in the conductivity of the air in both cylinders may be divided into two parts and ascribed to different causes; the one being associated with some change in the surface of the metals used in the construction of the cylinders.

Excerpt from The Radioactivity of Lead From these observations it would appear that the rise in the conductivity of the air in both cylinders may be divided into two parts and ascribed to different causes; the one being associated with some change in the surface of the metals used in the construction of the cylinders. And the other with some substance which becomes diffused throughout the air, and can be blown out with it. With cylinder No. 1 the part due to the first cause was very small, and in no case exceeded 10 or 12 per cent. Of the minimum reading obtained for the conductivity. The second part, too, was very definite with this cylinder, and when the maximum conductivity had been reached it corresponded to a reading of between 25 and 3 divisions per minute.
