The following earthen water filter will effectively remove radioactive particles from water…
All soil found around the United States include different combinations of the following three things… sand, silt, and clay. With that said, the soil type that’s best for a earthen water filter to remove radioactive particles is that with a high clay content.
Clay binds well to radioactive particles. If radioactive fallout has contaminated the water supply, earth filters utilizing clay type soil, will do well at removing radioactive particles from the water.
According to the American Civil Defense Association, this method is better than distillation, ion-exchange filters, or charcoal filters for this purpose.
