Incidentally, its interesting to compare US regs to Canadian ones :


http://laws.justice.gc.ca/en/n-28.3/sor-2000-207/154139.html
Nuclear Substances and Radiation Devices Regulations
SOR/2000-207
Registration 31 May, 2000
NUCLEAR SAFETY AND CONTROL ACT
<SNIP>

SCHEDULE
(Section 1)

EXEMPTION QUANTITIES

Column 1                                              Column 2
Radioactive Nuclear Substance          Quantity (in Bq)

<SNIP>
Uranium (natural) in non-dispersable form  1 x 10^7
<END QUOTE>

..............I haven't calculated how much mass 10 MBq of NU represents,
but considering the long half-life, it sounds like it could be quite a bit.
