Health Impacts of Nuclear War Act of 2023

HR 4703, the Health Impacts of Nuclear War Act of 2023, requires the U.S. Secretary of Health and Human Services to establish a 5-year research program studying long-term health effects from nuclear war's environmental consequences, such as cancer from increased UV radiation, malnutrition from crop failures, and disease spread due to extreme cold. It authorizes $10 million annually for 2024-2028 to fund research grants for nonprofits, universities, and research institutions. The bill mandates a comprehensive assessment of U.S. health system readiness to address these impacts, including identifying preparedness gaps and recommending countermeasures. This assessment must be submitted to Congress within one year of enactment, with coordination across multiple federal agencies.
