Downwinder Claims: Eligibility & Documentation Guide

Filing a successful Downwinder claim requires proving physical presence in designated areas during specific mid-century atmospheric testing windows, along with providing evidence of a qualifying medical diagnosis. As an independent archival research resource, this guide provides the directories and strategies needed to locate the primary and secondary evidentiary records required by the Department of Justice.

Note: As of August 2026, the Department of Justice is experiencing a six-month processing backlog for RECA claims. Careful documentation assembly prevents further delays.

Eligible Regions and Timeframes

To qualify, claimants must prove physical presence for at least one year between January 1951 and November 1962 (or September 1944 to November 1962 for New Mexico), or the entire month of July 1962, in the following areas:

Establishing Physical Presence & Overcoming Missing Records

Locating mid-century residency records is often the most significant hurdle when proving a claim timeline. Whether you have primary documents or need to rely on secondary sources, careful research is essential.

Navigate municipal archives and locate primary sources like property deeds and tax records. When primary records are inaccessible, learn how to utilize secondary evidence such as school yearbooks, church records, affidavits, and historical directories to build an undeniable timeline of residency.

Understanding Survivor Claims

If an eligible individual passes away before filing or receiving their payment, federal law allows their surviving family members to apply for the $100,000 compensation on their behalf. The compensation is distributed as a single lump-sum payment to the first living category of relatives according to a strict legal "order of precedence":

  1. Surviving Spouse: If the qualifying individual was married at the time of their passing, the surviving spouse is first in line to receive the benefit.
  2. Surviving Children: If there is no surviving spouse, the compensation is distributed in equal shares among all of the deceased individual's surviving children.

Filing a survivor claim requires proving the deceased family member's eligibility (medical and residency records) as well as verifying the survivor's legal relationship. Additional mandatory documentation includes a formal death certificate signed by a physician, and proof of relationship, such as a marriage certificate for a spouse or birth certificates for children.

Submitting Your Claim

It is critical to completely assemble all required documentation prior to filing your claim. Submitting an incomplete application will trigger deficiency notices and delay processing. All RECA claims must be filed before the statutory deadline of December 31, 2027. Once your evidentiary file is fully compiled, select the appropriate filing guide below:
