The great insolubility of radium sulfate (at 20 °C, only 2.1 mg will dissolve in 1 kg of water) means that it is one of the less biologically dangerous radium compounds. [6] The large ionic radius of Ra 2+ (148 pm) results in weak complexation and poor extraction of radium from aqueous solutions when not at high pH. [7]
Naturally occurring radioactive materials (NORM) and technologically enhanced naturally occurring radioactive materials (TENORM) consist of materials, usually industrial wastes or by-products enriched with radioactive elements found in the environment, such as uranium, thorium and potassium-40 (a long-lived beta emitter that is part of natural potassium on earth) and any of the products of the ...
Potassium-40 (up to 88% of total activity), carbon-14 (14 C), radium-226, uranium-238 and rubidium-87 (87 Rb) are found in ocean waters. Moreover, in groundwater abound radius radioisotopes such as radium-226 and radium-228 (228 Ra). [7] [8] They are also habitual in building materials radionuclides of uranium, thorium and potassium (the latter ...
