Betreff: Thorium in uranium ores.





Radsafers



Does anybody know of any references that gives the amount of thorium in

uranium ores?



-------------------------



John,



Since the (geological) origin of uranium ores differs extremely and as well

the origin of thorium, you should be aware, that there is no answer to your

question!!!! You can only do chemical analysis on your particular uranium

ore. Furthermore you did not mention the isotopes of thorium you are looking

for. Their abundance and ratio is not constant.



Best regards,



Franz
