The y-ray induced oxidation of Fr+2 ion in dilute aqueous solution

In 1895, Roentgen (1) discovered that invisible rays emanating from an electrical discharge tube produced blackening of a covered photographic plate. In the following year Beoqueral (2) observed a similar phenomenon produced by invisible rays from uranium-containing compounds. These were the first o...

Description
Summary:In 1895, Roentgen (1) discovered that invisible rays emanating from an electrical discharge tube produced blackening of a covered photographic plate. In the following year Beoqueral (2) observed a similar phenomenon produced by invisible rays from uranium-containing compounds. These were the first observations of a chemical change produced by ionizing radiations. The discovery of the radioactivity of radium by Mme. Curie (3) in 1898 led to the observation of a multitude of other effects produced by these radiations. For example, it was a matter of great concern that aqueous solutions of radium compounds continuously evolved hydrogen and oxygen.
