Ciro Santilli finds it interesting that radioactive decay basically kickstarted the domain of nuclear physics by essentially providing a natural particle accelerator from a chunk of radioactive element.
The discovery process was particularly interesting, including Henri Becquerel's luck while observing phosphorescence, and Marie Curie's observation that the uranium ore were more radioactive than pure uranium, and must therefore contain other even more radioactive substances, which lead to the discovery of polonium (half-life 138 days) and radium (half-life 1600 years).
Glass with Uranium added to it to become fluorescent due to Uranium's chemical properties. This is unrelated to Uranium's nuclear properties.
However it was this fluorescence that led Henri Becquerel to discover radioactivity while studying fluorescence, which led him to have Uranium compounds and photographic material in close proximity. I love science I guess.
