Depleted Uranium Resources
Depleted Uranium (DU) is a complex issue with significant implications for human health, the environment, and international law. This page serves as a hub for understanding DU, its impacts, and the global efforts to address its use.What is Depleted Uranium?
- Definition and Properties: Depleted uranium is a by-product of uranium enrichment, where the more radioactive isotopes are removed for nuclear fuel or weapons. While “depleted,” it remains a heavy metal with chemical toxicity and a radioactive half-life of 4.5 billion years, retaining over half the radioactivity of natural uranium. Its high density makes it attractive for military applications.
- Uses of DU: Primarily used in military applications for armor-piercing munitions and as a component in tank armor. It also has civilian uses as counterweights in aircraft, radiation shielding, and in medical equipment.

Health Effects of Depleted Uranium Exposure
Exposure to DU can pose both chemical and radiological health risks. Concerns are particularly high for those in areas where DU weapons have been used or where DU fragments remain.- Mechanisms of Exposure: Inhalation of DU dust and particles (especially after impact), ingestion of contaminated food or water, and embedded fragments from wounds.
- Key Health Concerns:
- Chemical Toxicity: Primarily affects the kidneys, potentially leading to renal impairment. Like other heavy metals, it can also impact other organs.
- Radiological Toxicity: While less radioactive than natural uranium, internal exposure to alpha particles (from inhaled or ingested DU) can cause cellular damage and increased cancer risk over time, particularly lung cancer.

- World Health Organization (WHO) – Depleted Uranium Fact Sheet (Includes health sections)
- UN Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) (Search for reports on uranium/internal exposure)
- VA Public Health – Depleted Uranium Research & Reports
Environmental Impacts of Depleted Uranium
The use of DU weapons leaves behind contaminated battlefields and firing ranges, posing long-term environmental challenges.- Contamination Pathways: DU particles and fragments can contaminate soil, water, and air, leading to potential bioaccumulation in the food chain.
- Post-Conflict Assessments:
- UN Environment Programme (UNEP) – Depleted Uranium: Environmental Assessment (Reports from the Balkans, Iraq, etc.)
- Remediation Technologies: Methods for cleaning up DU-contaminated sites, including physical removal of fragments and chemical stabilization techniques to immobilize the uranium in the soil.
- International Atomic Energy Agency (IAEA) Publications (Search for DU remediation)
- Google Scholar Search: Depleted Uranium Remediation (For academic papers)
International Efforts & Advocacy
A global movement of NGOs, scientists, and activists are working to ban DU weapons and address their legacy.- International Coalition to Ban Uranium Weapons (ICBUW): A global coalition dedicated to campaigning for a ban on the use, transport, manufacture, sale, and export of all conventional weapon systems containing uranium. They also advocate for health monitoring, compensation for affected communities, and environmental remediation.
- International Depleted Uranium Study Team (IDUST): An NGO of researchers, activists, and scientists focused on stopping the use of DU in military weapons and commercial products.
- Relevant International Laws and Resolutions:
- International Humanitarian Law (IHL) & Human Rights Law: Arguments are made that DU weapons violate principles of IHL due to their indiscriminate nature and long-term harm.
- UN General Assembly Resolutions: A series of resolutions have expressed concern over the use of armaments containing depleted uranium.
- Example UNGA Resolution on DU (e.g., A/RES/78/33) (You can search for specific resolutions on undocs.org)
- Country-Specific Bans/Moratoriums: Examples of countries that have banned the use of uranium in conventional ammunition.
- ICBUW – States Parties (Lists countries that have taken action)
- Andorra Law (example of a national ban) (This link is to a specific law in Catalan, demonstrating the type of link needed)
