    Physics Regarding postdoc

    I have worked on environmental radiation levels n determining the radioactivity in the environmental samples. I would like to do post doc in the field. I request to suggest me the posts available all over the world.

    Correlation between macronutirients and radionuclides

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

    Granulometric analysis

    thank you for the answer sir, the link i went through is also useful in clarifying the doubts.

    Correlation between macronutirients and radionuclides

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

    Correlation between macronutirients and radionuclides

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

    Granulometric analysis

    thanks for the reply, do there exists any relation between the minerals (Zn, Cu, Mn, Fe) that is found in the sediments with that of radionuclides (U, Th, K)?

    Granulometric analysis

    why do we need to determine the particle size while estimating the activity of radionuclides? is there any relation between the particle size (sand, silt and clay) and primordial radionuclide? will the content of uranium, thorium and potassium rely on particle sizes?

    Regarding minerological analysis

    which oxide is responsible for the increase of uranium -238 in the sediments of rivers. is it U(IV) oxide is soluble or U(VI) is soluble in water?

    Regarding minerological analysis

    Uranium can exist in five oxidation states: +2, +3, +4, +5 and +6. However, only the +4 and +6 states are stable enough to be of practical importance. Tetravalent uranium is reasonably stable and forms hydroxides, hydrated fluorides and phosphates of low solubility. Hexavalent uranium is the...

    Regarding minerological analysis

    why we need to find the minerals in the sediments while estimating the amount of radionuclides. although there exist a cation exchange capacity in the minerals, do they actually concentrate the primordial radionuclides in them. further on granulometric analysis, do the clay particles retain the...
