About Radium
Radium is a rare radioactive element found as a radioactive decay product in some uranium minerals, in amounts as small as 1/7 gram per ton of uraninite.

Although radium does not appear in the formula of any valid mineral species, the unapproved varietal name radiobarite describes a variety of barite with appreciable radium content. Radium is chemically very similar to barium so substitution is quite likely.

The substitution of radium for barium is also given as the explanation as to why brazil nuts are 1000 times more radioactive than other similar foods (40-260 Bq/kg) as the extensive root systems of the brazil nut tree help it absorb more barium (and along with it radium) than other similar plants.
