[From uranium] there are present at least two distinct types of radiation one that is very readily absorbed, which will be termed for convenience the α radiation, and the other of a more penetrative character, which will be termed the β radiation.

Radioactivity is shown to be accompanied by chemical changes in which new types of matter are being continually produced. .... The conclusion is drawn that these chemical changes must be sub-atomic in character.
