一 | 中新网衡阳8月21日电 (夏亦可)南华大学核科学技术学院韦悦周教授团队从稀土矿渣中直接分离获得高纯度阿尔法核素铅-212及其前体核素钍-228，成功实现单批次从公斤级稀土矿渣中分离提取158微居里的铅-212/铋-212。该成果近日通过中国同位素与辐射行业协会组织的科技成果鉴定，认为项目总体技术达到国际先进水平，其中单次回收率达到国际领先水平。韦悦周教授(左二)在带领团队成员做实验。

三 | 但目前铅-212提取工艺复杂、产量低、价格高，相关靶向药物难以推广应用，中国医用核素主要依赖进口。 As energy prices in Europe rise, Russia’s Security Council Chairman Dmitry Medvedev poked fun at German Chancellor Olaf Scholz, quipping on social media that the latter might be the only person in Europe who can take a decent shower now.,Referencing his March 30 post on Telegram in which he suggested that measures such as suspending the Nord Stream 2 pipeline would be the “best way to leave Europe without gas,” Medvedev remarked that European politicians have almost managed to achieve the “perfect combo” he outlined over four months ago, with gas futures prices in Europe now exceeding $2,800.,“What would happen to the price by the end of the year? $3,000? $4,000? Any higher bids?” he inquired in his recent post.,Medvedev’s remark about Scholz comes after the German chancellor shared some information about his showering habits during the Federal Government Open Day last weekend.,When a DW TikTok “Berlin Fresh” reporter asked Scholz how often he showers, the chancellor promptly responded: “every day.”,His response, however, apparently did not sit well with at least some people in light of the German government having asked citizens to “shower less because of the energy crisis,” as DW put it.,“So, it's just ordinary citizens that should not shower in support of Kiev,” one netizen mused.,WorldTwo Women Bare Their Breasts During Photo Op With German Chancellor Olaf ScholzYesterday, 15:57 GMT,The United States and its European allies have enacted several rounds of economic sanctions against Russia, including targeting Russian energy exports, over Moscow’s ongoing military operation in Ukraine.,The sanctions, however, have backfired spectacularly, leading to a steep increase in energy prices in the very countries that enacted them.。　　研究团队独辟蹊径，向独居石加工镭渣溶解液中引入特殊阴离子，使铅-212形成“阴离子络合物”，再利用自主研发的多孔二氧化硅负载型阴离子交换树脂，将其从含20多种金属杂质的溶液中精准“识别”并“抓取”出来。这项技术将富含放射性镭的废渣“化害为利、变废为宝”，有望打破全球医用阿尔法核素供应短缺困局。　　经检测，提取的铅-212产品核素纯度高达99.9%，单次回收率高于90%，钍-228单次回收率达到85%以上，工艺具备向中试放大推进的条件。围绕该技术已形成自主知识产权，申请发明专利6项，发表SCI论文10篇。

四 | 　　团队研究显示，仅约10吨镭渣即可提取1居里的铅-212，理论上可供66名癌症患者治疗使用。镭渣料液放置衰变约4天后可再次提取，循环利用多次。若每年处理50吨镭渣，可制备365居里铅-212，可供约24000名癌症患者使用。

五 | 团队同时能从镭渣中直接分离提取钍-228，其半衰期为1.9年，经衰变生成铅-212，适合远距离输送，可为国内外铅-212核药制备提供充足原料保障。　　目前该技术正在开展中试研发，计划2至3年后实现大批量制备，产能逐渐扩大至每日1居里以上。“结合中国丰富的稀土矿渣资源，可构建不受任何外部供应制约的制备网络。”韦悦周说。
