Bayleyite

Named for Professor William Shirley Bayley, former American mineralogist and geologist at the University of Illinois who also worked for the United States Geological Survey.  Bayleyite is a rare mineral that can be found in localities in the United States, Canada, Morocco, Argentina, France, and Israel, among only a few others. It occurs as a coating or efflorescence along with other secondary uranium minerals and may be of post-mine origin, and is found typicality in sediment-hosted uranium deposits. Bayleyite is soluble in water and can rapidly dehydrate when exposed to air. It is quite radioactive and has a weak fluorescence of yellow-green to pastel green under both long-wave and short-wave ultraviolet light.

Becquerelite

Named after Antoine Henri Becquerel, the French physicist who discovered radioactivity in 1896. Becquerelite is a rare mineral that occurs as a weathering product of uraninite in oxidized uranium deposits and can also be found, albeit rarely, in pegmatites. Localities include in the Democratic Republic of the Congo, Austria, England, France, the United States, Canada, and Australia, among a few others. Becquerelite is highly radioactive.
