The British Nuclear Testing Programme: One of the gravest state injustices of our time?

Radiation exposure, that has caused decades of suffering and unimaginable loss for our servicemen, their families, and indigenous communities, during Britain’s nuclear testing programme in the 1950s and 60s may yet stand as one of the gravest state injustices of our time.

For seventy years, governments of every stripe have held the same line: Radiation exposure at Kiritimati (Christmas Island, in the Pacific) was negligible; contamination was minimal, contained, and harmless; those stationed there faced no meaningful risk. That position has now been shaken. In February this year, journalist Susie Boniface uncovered the findings of a 2025 FOI request to the Atomic Weapons Establishment (AWE) which brought to light a critical document identifying elevated radiation levels that personnel were very likely exposed to. The claim that these veterans faced no risk has been turned on its head.

The servicemen themselves always knew they had suffered harm. Many developed rare cancers and a range of serious conditions; too many died young. Those who were lucky enough to live longer often endured a raft of chronic health complications, miscarriages and stillbirths in their families, and severe health complications faced by their children. Independent studies suggested exposure levels were comparable to clean-up workers at Chernobyl, yet the Ministry of Defence and successive governments leaned on selectively chosen research to dismiss any link.

Central to that denial was the 1993 Clare Report, which assessed environmental monitoring data from Kiritimati in 1957–58. It has been cited repeatedly in official statements and legal defences. But a 2014 FOI request prompted the MoD to commission a fresh review of that report and related data held by AWE. Two AWE analysts carried out a deeper examination, with far-reaching implications.

A draft of their extended analysis, revealed through the 2025 FOI, directly challenges the Clare Report’s credibility. It found missing records, incorrect tables, and mismatched samples. In short, the data was incomplete and inaccurate. More importantly, it identified previously overlooked spikes in environmental radiation, including readings taken during fish sampling immediately after test detonations in inhabited areas. Radiation levels were far in excess of the local norm. Fallout, the analysts concluded, was a plausible explanation.

The implications are stark.

For decades, veterans were told they had not been put at risk. Grieving families were told there was no connection. Courts, Parliament, and the public were told the same. The newly uncovered data tells a different story.

It points to elevated radiation not only in the environment but in fish, the very food servicemen were catching and eating regularly. With desalinated water in use, drinking supplies may also have been compromised. In a hot climate where food and water intake was high, exposure was not just external; it was likely ingested, compounding the risk of tissue damage and hereditary harm.

The report also exposes that the system of monitoring was virtually non-existent. Many servicemen were never issued film badges to measure exposure. The absence of records has, conveniently, made denial easier.

The authors are unequivocal: the Clare Report -used to defeat legal claims and deny compensation- was flawed. At best, this reflects systemic failure. At worst, it points to a cover-up.

They went further still, warning that their findings could “challenge the validity of statements” made by government and potentially reopen past legal decisions. Yet instead of being published, the analysis was buried for over a decade.

This goes to the heart of trust between the state and those who serve it. Because when those in uniform are sent to carry out dangerous duties, they do so on the understanding that their Government will act with honesty, transparency, and integrity about the risk they face. That trust has sadly been broken. So now, we have a moral and legal duty to put this right, with a full inquiry, full transparency, and fair compensation.

For too long, our nuclear test veterans have been told there is no evidence to support their claims and they have carried the burden of proof, when the state itself held the evidence all along. After seventy years, truth and justice are the very least we owe them.
