Breakthrough Study Bolsters RECA Claims for New Mexicans Exposed to Trinity Test Site Radiation

Plutonium Detections From Trinity Test Discovered 78 years After Test – Confirm RECA Must Be Expanded

Located in the Tularosa Basin in southern New Mexico, the Trinity Test Site marks the location of the first detonation of a nuclear weapon. Christopher Nolan’s “Oppenheimer” would have you believe this area is desolate, inhospitable and uninhabited. Contrary to this narrative and popular opinion, The area where the Trinity test occurred was not  uninhabited. There were more than 13,000 New Mexicans living within a 50-mile radius. Many of those children, women and men were not warned before or after the test. The event marking the dawn of the nuclear age in July 1945 ushered in decades of health issues for residents living downwind due to exposure to radioactive fallout. The long-lasting impact of radiation exposure is a painful legacy that the New Mexican communities have had to bear.


New preliminary information strongly supports Radiation Exposure Compensation Act (RECA) status for New Mexicans downwind of the Trinity Test Site. In the past weeks, Michael E. Ketterer, (Professor Emeritus, Chemistry and Biochemistry, Northern Arizona University, Flagstaff, AZ) has completed a short “proof of principle” study that directly investigates where plutonium in soils originates by analyzing isotopic ratios, in a known portion of the Trinity Test plume.

Dr. Ketterer sampled soils along highways NM 42, US 54, NM 55, US 60, and US 380. The isotopes show that there is definitely plutonium from the Trinity Test in the northeast plume, and distinguishes it from global (stratospheric) background and New Mexico regional background from Nevada Test Site fallout. Soils along all five of these highways contain plutonium that reflects mixtures of Trinity Test debris and global/Nevada regional background fallout; in some cases, nearly 100% of the Pu originates from the Trinity Test.

Does New Mexico Deserve Downwinder Status: Definitely Yes, as Evident Via Plutonium Isotopes in 2023 Soil Samples

Introduction/objective: to investigate whether plutonium from the July 16, 1945 Trinity Test can be identified in contemporary soils and dusts near the Trinity Site. A proof-of concept study was conducted via a small-scale July 2023 collection of soil samples along five public highways transecting the areas reported to be most affected (refer to 239+240Pu deposition inventory map from Beck et al., 2020). More-distant soil samples were obtained from the Carson National Forest near Truchas, New Mexico.

Holtec International, the U.S. Federal Government, and the State of New Mexico – What Do We Know?

Nuclear power is a trending topic lately. What’s missing from most of these conversations is the nitty gritty details of the nuclear waste produced from nuclear power plants, and how to handle it. In mainstream and social media, nuclear is often hyped up as a climate solution and the issue of what to do with the waste is promoted as being nearly or already solved. Unfortunately this conception is entirely inaccurate. Most people don’t think about the problem of nuclear waste on a frequent basis, however New Mexicans are often forced to confront it whether we like it or not (spoiler: most of us DON’T).

New Mexico has the Waste Isolation Pilot Plant (WIPP) in the southeastern corner of the state, where radioactive waste is stored in a salt formation repository located deep underground. WIPP has been open since 1999, and now federal regulators are currently considering another facility that would store up to 175,000 metric tons of high-level radioactive nuclear waste. The new repository is called a “HI-STORE Consolidated Interim Storage Facility” by Holtec International, the New Jersey-based company who owns the private waste facility, and the waste would be transported in from nuclear reactors around the nation. The Nuclear Regulatory Commission issued Holtec a license for this project on May 9, 2023.
