Like the natural uranium ore, DU is radioactive. DU mainly emits alpha particle radiation. Alpha particles don't have enough energy to go through skin. As a result, exposure to the outside of the body is not considered a serious hazard.

Normal functioning of the kidney, brain, liver, heart, and numerous other systems can be affected by uranium exposure because uranium is a toxic metal, although less toxic than other heavy metals, such as arsenic and mercury. It is weakly radioactive but is 'persistently' so because of its long half-life. The Agency for Toxic Substances and Disease Registry states that: "to be exposed to radiation from uranium, you have to eat, drink, or breathe it, or get it on your skin." If DU particles do enter an individual, the type of danger presented—toxic vs. radiological—and the organ most likely to be affected depend on the solubility of the particles.

Both depleted uranium and radon can be dangerous to the human body, but they pose different types of risks and have different effects.

Depleted uranium (DU) is a byproduct of the uranium enrichment process, and is used in armor-piercing ammunition and other military applications due to its high density and hardness. DU is only weakly radioactive, but it can pose a health risk if it is ingested or inhaled as fine particles. DU particles can cause damage to internal organs, especially the kidneys, and may also be linked to an increased risk of cancer.

Radon is a naturally occurring radioactive gas that is produced by the decay of uranium in soil and rocks. Radon can seep into buildings through cracks in the foundation or other openings, and can accumulate to high levels in enclosed spaces. Radon exposure is the leading cause of lung cancer in non-smokers, and can also cause other respiratory problems and increase the risk of other types of cancer.

Both depleted uranium and radon can be dangerous, but the risk and severity of the health effects depend on the level and duration of exposure. The health effects of depleted uranium are primarily due to its chemical toxicity, while the health effects of radon are primarily due to its radioactivity. It's important to take appropriate precautions to minimize exposure to both depleted uranium and radon, and to follow guidelines and regulations for their safe handling and disposal.
