Becquerel in 1896, it was noticed that some minerals of uranium, such as See also:

PITCHBLENDE, or URANINITE

pitchblende, were more active than the See also:

ELEMENT (Lat. elementum)

PROCESS

process of fractionation, with the result that in 1898 they announced the existence in it of two highly radioactive substances, polonium and radium. In subsequent years they did much to elucidate the remarkable properties of these two substances, one of which, polonium, came to be regarded as one of the transformation-products of the other (see See also:
