About Radian BariteHide

Formula:
(Ba,Ra)SO4
Colour:
White
Lustre:
Vitreous
Hardness:
3 - 3½
Crystal System:

Name:
From radium replacing barium and from the Greek, baryos, "heavy."
A variety of Baryte

A "variety" of baryte containing trace amounts of radium. The activity of 226Ra in the material from Ohře Rift area, Czech Republic, may reach 8 Bq/g. Scaly precipitates on oil industry equipment may show the radioactivity as high as 103 Bq/g.
