Radiation Safety Practice Exam

In terms of health risks, what does depleted uranium also present apart from radiation risk?

1. Metabolic risks

2. Biological hazards

3. Chemical hazards

4. Thermal hazards

The correct answer is: Chemical hazards

Depleted uranium presents chemical hazards in addition to its radiation risks. Depleted uranium is a dense metal that is often used in military applications and armor-piercing ammunition. When depleted uranium particles are ingested or inhaled, they can cause chemical toxicity, particularly to the kidneys. This chemical toxicity arises because uranium is a heavy metal that can interfere with biological processes in the body. Aside from the radiological concerns that come from exposure to ionizing radiation, the potential for chemical effects from depleted uranium is significant. The kidney is especially vulnerable to damage from high levels of uranium exposure, which can lead to nephrotoxicity, affecting kidney function and potentially leading to long-term health issues. In addition to these concerns, while other forms of hazards exist, such as metabolic or biological hazards, the primary health risk associated with depleted uranium exposure is its potential as a chemical toxicant. Therefore, the recognition of depleted uranium as a source of chemical hazards is critical in assessing the overall health risks it presents.
