Newly uncovered emails reveal that government lawyers were aware troops were exposed to radioactive fallout during nuclear testing on Christmas Island but did not disclose this information in court. The correspondence, obtained through Freedom of Information requests, shows that senior officials at the Treasury Solicitor’s Department received a whistleblowing report in November 2014 indicating such exposure, just weeks after a judge ordered renewed legal hearings on the matter. Despite this, the evidence was not presented during court proceedings, which later collapsed due to insufficient proof that ex-servicemen had been exposed to radiation.

The controversy centers on nuclear tests conducted under Operation Grapple in the late 1950s, during which radioactive fallout was detected in the environment surrounding the island’s main military camp. Two whistleblowers discovered evidence of contamination in fish, rain, seawater, and air—a finding that contradicted the Ministry of Defence’s (MoD) previous assurances that no personnel had been put at risk.

One case drawing public attention involves the late Barry Smith, an RAF serviceman deployed to Christmas Island in 1959 to assist in decontamination efforts by cutting the hair of troops involved. Over subsequent decades, he experienced persistent skin issues attributed initially to “sunburn” and received a small compensation payment. Eventually diagnosed with pancreatic cancer, Barry Smith died before the MoD authorized a formal hearing of his claim. His widow, Anna Smith, fought unsuccessfully for a war pension, with her claim denied on the basis that her husband had not been in a contaminated area.

Emails dated November 27, 2014, show that a desk officer at Veterans UK, the war pensions agency, was alerted to changes in the official stance on fallout levels. Upon receiving an early version of the whistleblowers’ report, he questioned whether the new information should be escalated to legal counsel. A line manager at the Atomic Weapons Establishment responded that a review had taken place, acknowledging that previous government denials “did not accurately represent the totality of this original data.” The official refrained from further email discussion, suggesting an in-person meeting instead.

Following these revelations, the information was circulated among various officials within the MoD before being forwarded to the Treasury Solicitor’s department for legal advice. At the time, an appeals judge had ruled there was “reasonable doubt” about the absence of fallout exposure and recommended the government consider releasing classified documents to aid the veterans’ cases.

Campaigners and families affected by the tests are now awaiting a parliamentary announcement concerning a two-year review into missing medical records and alleged human experimentation related to what has been termed the “Nuke Blood Scandal.” Critics argue that the government's failure to disclose known risks and evidence undermined justice for veterans and their families who have sought recognition and compensation for decades. The MoD has maintained its position on matters relating to contamination and veterans’ health but faces intensifying calls for transparency and accountability.
