| Possible Sources | Outcome |
|---|---|
| Air: In the air, uranium exists as dust. | The very small particles of uranium found in dust can fall onto water, plants, and land. Rain increases the amount of uranium in air that can settle to the ground. |
| Water: Uranium can be found in drinking water; higher levels tend to be from wells drilled in uranium-rich rock formations. | Uranium in surface water can be transported large distances. Some of the uranium in water will stick to sediment and other particles in the water. |
| Soil: Uranium is naturally present in nearly all rocks and soils. | Uranium deposited on land can mix into soil, wash into surface water, or stick to plant roots. |
| Food: Human daily intake has been estimated to range from 0.9 to 1.5 micrograms of uranium per day (µg/day). | Uranium can stick to plant roots. Unwashed potatoes, radishes, and other root vegetables are a primary source of uranium in the diet. |
