Through the crust of the earth , EPTWFU01 Water Filters the radionuclides from the decay of thorium-232 and uranium-238 are extensively distributed. Many of them are known as alpha-emitters. It includes radon, polonium, as well as radium. The uranium concentrations in the drinking water ware extremely variable, and it ranges from 0.02 to 200 ug per liter in the sources of the drinking water. Meanwhile, the content of thorium in the drinking water has not been extensively measured. However, its concentration in the human skeleton is around 1 fCi per gram of ask. As such, the abundance of uranium in the human skeleton is said to be 10 times greater. In the drinking water, studies have shown that the natural alpha-emitters are bone seekers. As such, radium -226 and radium -228 can have a great potential of producing harmful radiation doses to man. radiation The radium -226 fresh surface water content is variable, and it can range from 0.01 to 0.1 pCi per liter.
