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.
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?
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...
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...
