I wonder what makes I-129 a "radionuclide of interest". Its exceedingly long
half-life makes it essentially a stable element, no different than the stable
iodine that occurs naturally in most soils.

Hope you are all doing well. HP abstracts for the HP Society
Meeting in Sacramento,
California are out now, as a supplement to Health Physics magazine.
reading. One item is on DU by Bob Cherry.
Operational Radiation Safety (another HPS journal) has an article on
Decommissioning of the
Brookhaven Lab High Flux Beam reactor. Fuel and spent fuel are gone.
Heavy Water is gone.
Interesting reading. I guess that's one way of totally stopping the
tritium leak source term.
The offending leaking fuel storage pool was drained. Goodbye. Wonder
what they'll do with the
Brookhaven Medical Research Reactor. I don't think there was anything
wrong with it..
There's an abstract on the new Texas LLRW (Low Level Radioactive
Waste) facility and some
modeling they did. The radionuclides of interest are C-14, Tc-99, I-129,
possibly among others.
I guess tritium is not that big a deal in such a facility, due to its short
half-life. These radionuclides
are particularly mobile in the groundwater environment, as referred to in
my earlier RADSAFE
postings. These Texas folks did some computer modelling and describe what
they did. Wonder why
they didn't just use Femwater-BLT (Suen and Sullivan???), Lewater, Lewaste
or similar computer
codes. Last I heard, Femwater-BLT was available for use on a personal
computer. It is or was
available for a fee from the RSICC, the Radiation Shielding Information
Center at Oak Ridge
National Laboratory (USA). Other Radiation computer codes are available.
Finally, if you see a computer
code you are interested in, you can search it out on the internet, and then
email the original
programmers/designers for information on how to obtain such a computer
code. No big deal.
These newfangled small, modular reactors are also addressed in an
abstract. Sounds like
some of them will be deployed by the TVA, in the Tennessee Valley.
electricity for people/homes/businesses previously not on the electricity
NJ Nuke plants and workers, thanks for the 50% of the electricity (in
NJ) that you are providing to
air condition part of my home this summer!!!! Take Care...
