A research team from Oxford University in Cambridge, England, and the Pacific Northwest National Laboratory in Richland, Wash., found that radiation from plutonium degrades zircon-based ceramics far faster than previously estimated - in 1,400 years, rather than the 250,000 years that waste-management experts had suggested. Zircon has been touted as a useful material for immobilizing plutonium for storage in underground nuclear-waste dumps. (Plutonium used in nuclear reactors must be isolated for 250,000 years to ensure it becomes harmless, scientists say.) The results appear in the current issue of the journal Nature. _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
