[ RadSafe ] Limited Quantity

[Tung, Enoch]

Hi All,

 

Quick questions about LQ.

 

As per 10 CFR 49, limited quantities for liquid (normal form) is 10^-4 *
A2.

 

Now in table 173.435 there are some entries that show A2 (and A1) values
to be "unlimited".

ie.  I-129, Mn-53, Ni-59, etc.

 

Does this mean the limited quantity for those isotopes are also
unlimited?

In effect, there is no activity limit to ship those isotopes as Excepted
Package, as long as surface dose rate and TI criteria are met?

 

Thanks,

Enoch
