RE: Algae
At Hanford Site, the "tumble weeds" have been known to concentrate radioisotopes through botanical deposition. They spray paint them in case they break off and roll out of the RCA so they can be identified/dispositioned. Water soluable contamination can end up that way.

What do you mean by "biomagnification of uranium (& radium)"? Are you asking
about plants that concentrate uranium and/or radium.
If so, I've been around HP's that work at uranium mines and mills for
decades and have never heard it mentioned. I therefore assume that there is
no "biomagnification".

I have raised this inquiry few days to the list without any response.
I need information about biomagnification of uranium (& radium) by
different organism species (particular algae). Any information or
information sources is appreciated.
Regards.
