Understand your exposure risk and health implications from Agent Orange use during Vietnam War
Agent Orange was an herbicide sprayed extensively during the Vietnam War (1962-1970), affecting an estimated 2.1-4.8 million Vietnamese people and thousands of U.S. And allied service members. Contaminated with dioxin (TCDD), it caused documented health effects across generations, including various cancers, birth defects, and neurological conditions.
This tool helps you assess your potential exposure level and understand associated health risks based on your circumstances. Whether you served during the Vietnam era, lived in affected regions, or are a descendant of those exposed, this assessment provides personalized information about documented health effects and current support programs.
As of 2026, multiple countries recognize Agent Orange-related disabilities, and compensation programs continue to evolve. Use this tool to understand your situation and learn about available resources.
Agent Orange was a tactical herbicide sprayed by the U.S. Air Force during the Vietnam War (1962-1970) to defoliate jungle areas and destroy crops. Approximately 20 million gallons were sprayed across Vietnam, Cambodia, and Laos. The chemical was manufactured by several companies and contained dioxin (TCDD), a highly toxic contaminant that wasn't fully understood until after widespread use.
The term "Agent Orange" comes from the orange-striped barrels used to store it. It was one of several herbicides in the Agent series (Agent Pink, Agent Purple, Agent White), but Agent Orange was used in the largest quantities. The immediate effects were visible deforestation of millions of acres, but the long-term health effects proved far more devastating and continue today across generations.
Cancer: Multiple cancer types including lung, prostate, liver, and soft tissue sarcoma. Veterans and exposed Vietnamese populations show elevated cancer rates decades after exposure.
Birth Defects: Agent Orange is categorized as a teratogen, causing neural tube defects, cleft palate, club foot, and other developmental abnormalities in exposed children and grandchildren.
Chronic Health Conditions: Type 2 diabetes, heart disease, liver disease, neurological disorders, and immune system dysfunction. These conditions appear in first generation exposees and their descendants.
Generational Effects: Research documents that health effects pass to second and sometimes third generations. Vietnamese-American children of exposed parents show higher rates of birth defects. U.S. Veterans' children have elevated disease rates.
Mental Health: PTSD, depression, anxiety, and other psychological effects related to combat exposure combined with chemical contamination.
U.S. And Allied Service Members: Approximately 2.7 million U.S. Service members served in Vietnam. Of these, about 300,000 are estimated to have had direct Agent Orange contact. Australian, Korean, and New Zealand troops also served in spray-affected areas.
Vietnamese Population: An estimated 2.1-4.8 million Vietnamese civilians were directly exposed to herbicides. Millions more live in contaminated areas, particularly in central Vietnam where dioxin levels in soil remain elevated decades later.
Descendants: Children and grandchildren of exposed individuals show elevated rates of health problems, establishing Agent Orange's multigenerational impact.
Current Era: As of 2026, survivors and their descendants continue seeking medical care and compensation. Vietnam has established health monitoring programs, and the U.S. VA continues expanding eligible health conditions.
U.S. Veterans Administration: U.S. Veterans with service in Vietnam are eligible for presumptive conditions related to Agent Orange exposure. The VA recognizes 14+ conditions and provides healthcare, disability compensation, and survivor benefits. Vietnam-era veterans should register in the VA system and request Agent Orange screening.
Vietnam Government Programs: Vietnam recognizes Agent Orange victims and has established healthcare and compensation programs for Vietnamese citizens. The government provides monthly allowances and healthcare access to Agent Orange victims and their families.
International Programs: Canada, Australia, New Zealand, and South Korea have compensation programs for their veterans. Countries worldwide continue reviewing new scientific evidence for expanded benefit eligibility.
Healthcare Initiatives: Medical centers in Vietnam and the U.S. Specialize in Agent Orange health effects. Genetic counseling and preventive screening are available for exposed families. As of 2026, advanced testing for dioxin exposure is increasingly available.
Since the 1980s, hundreds of peer-reviewed studies have documented Agent Orange's health impacts. The International Agency for Research on Cancer (IARC) classified dioxin as a Class 1 carcinogen in 1997. Subsequent research has expanded understanding of:
Epigenetic Effects: Recent studies (2020s) show that dioxin exposure alters gene expression patterns that pass to offspring, explaining multigenerational health impacts without genetic mutations.
Mechanism of Action: Dioxin binds to the aryl hydrocarbon receptor (AhR), disrupting endocrine, immune, and reproductive systems. This explains the broad spectrum of health effects observed.
Soil Persistence: Dioxin remains in Vietnamese soils with half-lives of 10+ years. Testing of soil, water, and food in affected areas continues showing contamination decades after spraying ceased. This explains ongoing exposure risks for Vietnamese citizens.
