General Information
What is RECA?
The Radiation Exposure Compensation Act (RECA) is a federal program that provides compensation to individuals who developed certain illnesses after exposure to radiation from U.S. nuclear testing. This includes "Downwinders" who lived in affected areas during specific atmospheric testing windows.
Who qualifies as a Downwinder?
Downwinders are individuals who were physically present in designated areas during specific periods of atmospheric nuclear testing and later developed qualifying health conditions. The required timeline depends on the location:
- State of New Mexico: You must prove physical presence for a period of at least one year between September 24, 1944, and November 6, 1962.
- Designated Affected Areas (Other States): You must prove physical presence for a period of at least one year between January 21, 1951, and November 6, 1962, OR for the entire period beginning June 30, 1962, and ending July 31, 1962.

What geographic areas are covered?
To be eligible for compensation, the claimant must have been physically present in one of the following specific regions:
- Full States: Idaho, New Mexico, and Utah.
- Arizona Counties: Apache, Coconino, Gila, Mohave, Navajo, and Yavapai.
- Nevada Counties: White Pine, Nye, Lander, Lincoln, Eureka, and Clark (limited to townships 13 through 16 at ranges 63 through 71).
Eligible Downwinder regions based on the RECA claim form criteria.
The 2025 RECA Expansion Bill significantly widened the map. Crucially, it added New Mexico to cover the original 1945 Trinity Downwinders, while also expanding coverage across Arizona, Colorado, Idaho, Montana, Nevada, and Utah. While the program is broad, RECA.help is actively expanding support to assist claimants navigating documentation in these newly covered areas.
What cancers and conditions are eligible?
Eligible conditions include: Leukemia (except chronic lymphocytic leukemia), Multiple Myeloma, Lymphomas (other than Hodgkin’s), and primary cancers of the Thyroid, Breast, Lung, Stomach, Colon, Esophagus, Small Intestine, Pancreas, Bile Ducts, Gall Bladder, Liver, Kidney, Urinary Bladder, Brain, and Ovary.
The Science & History
Why are certain dates more significant for Downwinders?
Eligibility is tied to specific operations at the Nevada Test Site. Periods like Operation Plumbbob (1957) and Operation Dominic II (1962) are critical because the rush to beat international political deadlines resulted in condensed, high-intensity fallout releases.
What was the "1958 Moratorium"?
A voluntary "Gentleman's Agreement" between the U.S. and USSR. The pressure to test before the pause (Operation Hardtack II) and the "catch-up" testing in 1962 often led to testing in poor weather conditions, which maximized unplanned fallout in downwind communities.
How did fallout enter the food chain?
Through the "Milk Pathway." Radioactive isotopes like Strontium-90 fell on grass consumed by livestock. The radiation was then passed into the local milk supply and absorbed into the developing bones and thyroids of children.
Claim Assistance
What makes a Downwinder claim difficult?
Proving residency from decades ago is the primary challenge. Many records from the 50s and 60s were never digitized, are missing, or are incomplete. Success depends on precise medical coding and verifiable proof of residence during the exact testing windows.
What does RECA.help do?
We assist claimants with locating and organizing proof of residency and medical records that meet federal requirements, specifically for difficult cases where records are scarce.
Are you a law firm?
No. RECA.help is a consultancy resource. We do not provide legal representation. Our focus is strictly on documentation support and navigating the administrative hurdles of the application.
Do I need a consultant to file?
No. You can file on your own using free government resources. Assistance is simply an option for those who find the documentation process overwhelming or have complex residency histories.
How do I obtain the necessary medical records for a claim?
The Department of Justice requires contemporaneous medical documentation proving a qualifying diagnosis, with pathology reports or tissue biopsies considered the gold standard. Because many historical medical files have been periodically purged, tracking down decades-old documentation can be challenging. You can access direct online records request wizards and contact directories for major healthcare systems across the region by reviewing our RECA Medical Records Guide.
What records are accepted to prove my historical residency?
To establish physical presence during the required exposure windows, the DOJ requires contemporaneous documentation created at the time you lived there. Because a single record rarely covers an entire multi-year window, successful claims usually layer a mix of archival, municipal, and institutional records (such as census data, tax assessments, and school transcripts). For a complete breakdown of these sources and step-by-step instructions on acquiring them, see our comprehensive guide on our RECA Residency Evidentiary Records Guide.
