A worker was carrying out maintenance work close to an X-ray generator used to measure the thickness of steel sheets. The X-ray generator was operating while the maintenance work was in progress, whereas it should have been switched off in order to avoid all risk of accidental exposure of the maintenance personnel. The worker was exposed for about twenty minutes, with part of his body being directly within the radiation beam for about five minutes. The dosimetric reconstruction carried out following the incident, as part of the medical care given to the worker, concluded that a whole body effective dose of about 0.2 millisieverts (mSv) had been received, as well as an equivalent dose to the skin of about 2 Sieverts (Sv) on a highly localised surface area, corresponding to that directly exposed to the beam. The exposure received by this worker led to no immediate health effect, cutaneous in particular (burn, necrosis, etc.); however, given the highly localised but significant exposure of a part of the body, the need for specific medical follow-up will be examined.

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 […]
Kernenergie en veiligheid: A wargame sought to test if a major radiological release that would prompt the evacuation of millions of civilians in South Korea could distract key US allies from assisting and rebuffing an all-out military invasion of Taiwan. The short answer was yes. The game originally presumed that China, wanting to keep the […]
Big batteries and EVs to the rescue again as faults with new nuclear plant cause chaos on Nordic grids The Finnish nuclear power plant Olkiluoto was finally connected to the grid last year, at an estimated cost of €11 billion compared to the original budget of €3 billion. That cost blowout forced its developer, the […]
A vast subsea nuclear graveyard planned to hold Britain’s burgeoning piles of radioactive waste is set to become the biggest, longest-lasting and most expensive infrastructure project ever undertaken in the UK. The project [UK's nuclear waste dump] is now predicted to take more than 150yrs to complete with lifetime costs of £66bn in today’s money...The […]
Last year, the Dutch Province of Limburg started an alliance in which, besides the local government, research institutes, small nuclear reactor (SMR) developers, utilities, industrial customers and funders cooperated. With this "Limburg SMR alliance" Limburg tried to lead the way towards an SMR in Limburg. The preferred site for a first SMR would be Chemelot, […]
