Correlation between macronutirients and radionuclides

  • #1
do the presence of macronutrients (N,P,K) increase the amount of radionuclides (U,Th,K) in the sediments. how are they related?

Why should they?

As both exist in clay particles, that have high exchange capacity?

As Borek already told you, it would be good if you were to give us some more background for your question.
I told you already in another thread that thorium isn't mobile and therefore won't interact with clays.
For uranium google spits up quite some literature, e.g. :
http://tubaf.qucosa.de/fileadmin/data/qucosa/documents/6240/final version of Diss_SB_BM_BPF_Bibo.pdf
What I think is also important is the point that many fertilizers contain uranium or radium, especially phosphate fertilizers as they are produced from uranium containing phosphate ores.

i got the point regarding. thank you. since clay particles have high cation exchange capacity, why cant the radinuclides can be embbeded in clays??
