Rutherford and Soddy's research involved:

3)The theory that uranium successively disintegrated to lead

Radioactivity involves conversion of one atom of an element into another by particle decay or radiation. They stated the disintegration theory of radioactivity, also discovering a large number of radioactive elements.

They both got Nobel prizes as well.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
