Betreff: RE: Radioactive vinegar bottle ?!?!
Is the naturally occurring uranium or thorium used to make glass bottles
regulated by the NRC?
---------------------------------------------------
Uranium was used to color glass. In Europe it is not used any more since
long and I would be very surprised if it still would be used anywhere else,
especially since the same color can be produced easier and cheaper by other
means. Thorium was used to produce highly refractive optical glass, but
never for glass bottles. It is also used in small quantities as
anti-reflection shield for eyeglasses.
So I do not think that there is any concern about regulations.
