Rare-earth ores in southern China – all except for those in Inner Mongolia – contain radioactive substances that pose significant threats to human health and the environment. Other countries might worry about the health risk to workers in rare-earth processing, but that does not appear to be true of China.
当然，中国还拥有大量的廉价劳动力去处理矿石。中国南部地区的稀土矿（内蒙古地区除外）含有对人体和环境有害的放射性物质。其他国家或许会担心稀土处理过程中的工人健康问题，但对中国来说，这根本不是个问题。
