Correlation between macronutirients and radionuclides

[hariprasath]

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

 

[Borek]

Why should they?

 

[hariprasath]

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

 

[DrDu]

Yes, Macronutricient K increases radionuclide K

 

[hariprasath]

thank you sir.

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%20version%20of%20Diss_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 can't the radinuclides can be embbeded in clays??
