France’s Atomic Energy Commission (CEA) invested over €90,000 in a campaign to discredit research revealing the extent of radioactive contamination from nuclear tests conducted in French Polynesia in the 1960s and 1970s, according to documents obtained by Disclose and reviewed by Le Monde and The Guardian.
In 2021, the book Toxic—based on declassified archives—proved that France had systematically downplayed the impact of its nuclear tests. In response, the CEA printed 5,000 copies of a glossy brochure containing "scientific rebuttals," distributed across the islands, and sent a delegation in business class to Polynesia to meet with officials and media.
The Toxic investigation found that a single 1974 test alone exposed 110,000 people—nearly the entire population of Tahiti and nearby islands—to radiation levels high enough to qualify for compensation if they later developed one of 23 recognized cancers. However, the CEA has long disputed such estimates, drastically limiting eligibility for payouts. By 2023, fewer than half of the 2,846 compensation claims filed had been approved.
A parliamentary inquiry, set to conclude by the end of May, is examining whether France deliberately concealed the scale of the disaster. While France’s nuclear safety authority (ASN) has acknowledged "uncertainties in the CEA’s calculations," the commission’s military division continues to deny wrongdoing.
President Macron acknowledged France’s "debt" to Polynesia in 2021, yet over the past four years, the CEA has declassified just 380 documents, compared to 173,000 released by the military. Local communities still suffer from radiation-linked cancers, including thyroid disease, leukemia, and lung cancer.
"No nuclear test resulting in radioactive fallout can be called clean," admitted the head of CEA’s military division, undermining decades of official claims about the safety of France’s nuclear program.
