On October 27, 2005, the Nuclear Regulatory Commission (NRC) was notified by one of its radiography licensees that a potential overexposure may have occurred during radiographic operations. According to the licensee, a radiographer was disconnecting the source guide tube from the radiographic device and noticed that the source was not in the fully shielded position. The exposure device contained a 807 gigabecquerel (21.8 Ci) iridium-192 sealed source. The radiographer noticed that his pocket ion chamber was off-scale and notified the radiation safety officer (RSO). Because extremity dosimeters are not commonly used during radiographic operations, the RSO conducted a dose reconstruction. Based on the dose reconstruction, one individual may have received an extremity dose in the range of 3.3-3.6 Gy (330-360 rad), a dose in excess of NRC’s annual occupational shallow dose equivalent limit of 500 mSv (50 rem) to the skin of the extremity. Whole body dosimeter results revealed that the radiographer received a whole body dose of approximately 2 mSv (200 mrem). The radiographer was admitted to the hospital for observation and has been released.
On October 28, 2005, the NRC initiated an onsite inspection to review the circumstances that led to the event. Initial information obtained indicated the individual had worn his dosimeter on his hip and his body may have shielded the dosimeter. The NRC will conduct a reenactment and will use the information to perform dose estimates.

The Pacific News Bulletin (since September 1986) and its predecessor Pacific Bulletin was published for the Nuclear Free and Independent Pacific (NFIP) Movement by the Pacific Concerns Resource Centre (PCRC), first based in Petersham (Australia) and later at Suva on the Fiji Islands. The NFIP movement grew out of the first regional Nuclear Free Pacific […]
On 29 June 2026, the Urenco Group issued a statement announcing that the UK Government formally requested the company to support its effort "to re-establish a nuclear fuel cycle for reactor fuel for defence purposes." The UK Government announced its intent to re-establish this program in November 2024. This announcement is part of a broader […]
The Netherlands has agreed to allow Urenco to be used for the British military nuclear program. This clears the way for uranium enriched by Urenco to be used in nuclear weapons. With his decision, Foreign Minister Berendsen (CDA Christen Democrats) is departing from the principle that civilian and military nuclear applications must remain strictly separate. […]

Everywhere you look, the nuclear industry’s hype machine is in overdrive. Goldman Sachs, Microsoft, and the UK government all tout small modular reactors as the silver bullet for climate change and energy security. Tech billionaires are hiring nuclear veterans. Wall Street is whispering about “round-the-clock power” for artificial intelligence data centers. For those old enough […]
