[ RadSafe ] Long-lived radionuclides

[Robert J Gunter]

The problem with long lived radionuclides is they contribute to off-site
dose for a long time.  This is obvious, but they may become limiting factors
for waste pits in the long term when the "engineered barriers" break down.
We prefer to ignore the other stuff....

Could someone please explain why there is such inordinate concern about the 
 long-live radionuclides such as
 I-129, Pu-239, etc.
It seems to me that if long-lived species are of particular concern, we
should 
be most worried about the toxic stable elements (Pb, Cd, Hg, etc) which will

persist forever.

How does one separate the I-129 from seawater to heat it in a microwave oven

with lead so as to immobilize it as Prof Hyatt's technique prescribes?
