Rock samples from Oklo, some of them recovered during drilling campaigns, are stored in the headquarters of France\u2019s nuclear power and renewable energy company Orano. In early 2018, two half split drill-core samples were donated to Vienna\u2019s Natural History Museum. The donation was made possible by the financial contribution of Orano and France\u2019s Alternative Energies and Atomic Energy Commission (CEA), with the support of the French Permanent Mission to the United Nations and the International Organizations in Vienna. IAEA scientists helped when the sample was delivered to Vienna by monitoring radioactivity levels and facilitating the rock\u2019s safe handling.<\/p>\n
The two samples emit a radiation of approximately 40 microsieverts per hour if you stand 5 centimetres away from them, which roughly compares to the amount of cosmic radiation a passenger would receive on an eight-hour flight from Vienna to New York. The museum, which receives 750 000 visitors a year, is used to dealing with radioactive samples since it already displays a number of slightly radioactive rocks and minerals.<\/p>\n
\u201cWe want people to learn about natural radioactivity, to make them aware of the fact that radioactivity is all around us, that it\u2019s natural and that at low levels it\u2019s not dangerous. Radioactivity is in the floors and walls of our homes, in the food we eat, in the air we breathe, and even in our own body,\u201d said Ferri\u00e8re. \u201cWhat better way to explain this than by showing a real sample from Oklo, where nuclear fission occurred naturally billions of years ago?\u201d<\/p>\n
The permanent exhibition will show different sources of background radioactivity. Perhaps a world map with the distribution of radioactivity, a radiation detector or Geiger counter or a cloud chamber, will allow visitors to see exposure to natural radiation for themselves.<\/p>\n
\u201cRocks are like books. You can look at the cover and get some basic information, but it\u2019s when you open them that you get the full story,\u201d Ferri\u00e8re said. <\/p>\n","protected":false},"excerpt":{"rendered":"
Physicist Francis Perrin sat at a nuclearfuel-processing plant down in the south of France, thinking to himself: \u201cThis cannot be possible.\u201d It was 1972. On the one hand, there was a dark piece of radioactive natural uranium ore, extracted from a mine in Africa. On the other, accepted scientific data about the constant ratio of […]<\/p>\n","protected":false},"author":1,"featured_media":8723,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[7253],"tags":[],"class_list":["post-8724","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-noticias"],"acf":[],"yoast_head":"\n
