A study is made of three processes for the separation of thorium from uranium and rare‐earth elements in crude thorium nitrate solutions prepared by breakdown of monazite sand. Uranium may be separated from thorium and rare‐earth elements in a preliminary extraction with 5 or 40 vv tri‐n‐butyl phosphate TBP in xylene and the ...

Since uranium is relatively soluble it is not found in mineral sand placer deposits except when it is tightly incorporated into the crystal structure of stable minerals. Thorium however is very insoluble so thorium minerals are common in such deposits. Conversely there is no thorium in seawater but significant levels of uranium 0.003 ppm.
Terrestrial radiation refers to sources of radiation that are in the soil water and vegetation. The major isotopes of concern for terrestrial radiation are potassium uranium and the decay products of uranium such as thorium radium and radon.Note that terrestrial radiation includes an external exposure caused by these radionuclides.
