Re: Radioactive vinegar bottle ?!?!

[Kai Kaletsch <info@eic.nu>]

John,



Most U mines operating today grade between 1 and 20 % U on average. There

are always pockets with much higher grades. The upper limit is determined

only by the chemical form of the ore. (I think UO2 has the most U.)



There are some operations that produce U as a byproduct to gold or copper

etc and these grade lower in % U. There are also ISL (in situ leach)

operations where the grade may be lower.



BTW, in Canada, only Naturally Occurring Radioactive Materials (NORM) that

are not associated with nuclear energy are exempted form CNSC (Canadian

equivalent of NRC) regulation. I wouldn't doubt that the US has a similar

clause.



Regards,

Kai
