It leaves no ruin, no ash, no wound you can see. You don\u2019t need to touch it. You don\u2019t need to breathe it in. You simply pass by\u2014and it passes into you. No trace is left on the soil. But a trace is left in you. And when the next person passes, they too receive the signal. Yet the source remains\u2014unchanged, unweakened.<\/li>\n\n\n\n<li>Most poisons are spent as they harm. Gamma radiation is not. It accumulates elsewhere, silently, without diminishing its source. A kind of ambient inheritance.<\/li>\n<\/ul>\n\n\n\n<p><em>In a recent study, I calculated the gamma radiation field unleashed by humanity\u2019s Uranium-238 (U-238) legacy. The results show that this field is not temporary. It is already present, slow to mature, but geologically assured and radiologically significant, beyond safety thresholds.<\/em><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Mill tailings scattered across continents emit gamma radiation through uranium\u2019s progeny. This signal will slowly fade over the next half a million years\u2014but it will reach a baseline, unsafe value and will continue indefinitely.<\/li>\n\n\n\n<li>Meanwhile, depleted uranium stockpiles\u2014which emit almost no gamma today\u2014are quietly maturing. From a few thousand years onward, their gamma output will rise steadily, eventually overtaking significantly that of tailings, peaking in two million years, and continuing unabated into geological time.<\/li>\n\n\n\n<li>Most U-238 residues lie close to the surface\u2014mill tailings, depleted uranium (DU) stockpiles, weapons testing sites, contaminated soils from mining and from exploded DU munitions. Even when their radiation does not cause immediate harm, it defines a long-term environmental signal whose meaning we have barely begun to grasp.<\/li>\n<\/ul>\n\n\n\n<p><strong>This raises questions not only of science, but of ethics, inheritance, and imagination:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>What does it mean to leave behind a hazard that grows in potency over time?<\/li>\n\n\n\n<li>How do we warn future beings of a danger concealed in ordinary soil or dust?<\/li>\n\n\n\n<li>Should gamma radiation be seen not only as threat, but also as a marker of human agency?<\/li>\n<\/ul>\n\n\n\n<p><em>Nuclear waste lasts a long time. But U-238 isn\u2019t just persistent\u2014it performs. It changes. It regenerates. It returns. And surprisingly, we don\u2019t call it waste. We call it an industrial by-product.<\/em><\/p>\n\n\n\n<p><strong>And now we are not just leaving behind a signal\u2014we are leaving a body.<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>About 4.5 million tonnes of U-238, mostly in oxide form, now reside in uranium tailings, DU, and spent fuel. It is a real, physical legacy\u2014not symbolic, not speculative. This body must be put away\u2014not forgotten, but deliberately placed and traced. Shielded, marked, and remembered.<\/li>\n\n\n\n<li>We can still act. We can treat uranium\u2019s gamma legacy not as an afterthought, but as a defining part of our industrial inheritance. This won\u2019t undo the past\u2014but it may shape how future generations understand what we\u2019ve left them.<\/li>\n<\/ul>\n\n\n\n<p><em>We often speak of the nuclear age as bracketed\u2014confined by Cold War dates or the operational lifespan of reactors. But its material consequences are just beginning. Care begins by acknowledging and tending to what endures.<\/em><\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"984\" src=\"https:\/\/blogg.lnu.se\/unesco\/wp-content\/blogs.dir\/209\/files\/sites\/209\/2024\/11\/Claudio-P-2024-1024x984.jpg\" alt=\"Claudio Pescatore\" class=\"wp-image-3804\" style=\"width:336px;height:auto\" srcset=\"https:\/\/blogg.lnu.se\/unesco\/wp-content\/blogs.dir\/209\/files\/sites\/209\/2024\/11\/Claudio-P-2024-1024x984.jpg 1024w, https:\/\/blogg.lnu.se\/unesco\/wp-content\/blogs.dir\/209\/files\/sites\/209\/2024\/11\/Claudio-P-2024-300x288.jpg 300w, https:\/\/blogg.lnu.se\/unesco\/wp-content\/blogs.dir\/209\/files\/sites\/209\/2024\/11\/Claudio-P-2024-768x738.jpg 768w, https:\/\/blogg.lnu.se\/unesco\/wp-content\/blogs.dir\/209\/files\/sites\/209\/2024\/11\/Claudio-P-2024-1536x1476.jpg 1536w, https:\/\/blogg.lnu.se\/unesco\/wp-content\/blogs.dir\/209\/files\/sites\/209\/2024\/11\/Claudio-P-2024-2048x1969.jpg 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\"><em>Claudio Pescatore is a member of the UNESCO Chair on Heritage Futures at Linnaeus University<\/em><\/figcaption><\/figure>\n\n\n\n<p>Read more: <a href=\"http:\/\/www.nukleonika.pl\/www\/back\/full\/vol70_2025\/v70n2p031f.pdf\">http:\/\/www.nukleonika.pl\/www\/back\/full\/vol70_2025\/v70n2p031f.pdf<\/a>\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>By Claudio Pescatore What if the true monuments of the nuclear age are not vaults, vitrified blocks, or warning markers\u2014but fields of invisible light?
