[ RadSafe ] Radiation from Uranium Oxide

[Jeff Terry]

Kai is definitely correct .001/10.96 is 9x10-5 cm^3. Sorry, I  
converted to mg in my head instead of using google. What kind of  
people use powers of ten instead of nice round numbers like 3/32 ; ).

My numbers were for .1 gram or 100 mg.

For 1 mg, it would be  .3 mm by .3 mm by 1 mm or a 0.5 mm diameter  
sphere.

Thanks Kai,

Jeff
