BBC中文网日本特约记者
日本内阁府的原子力安全委员会和政府旗下的原子能安全保安院将东京电力福岛第一核
电站3月泄漏核辐射事故的评估等级提升至七级。
日本核安全官员宣布上调福岛核电站事故等级
这是国际核能事故等级（INES）迄今为止的最高级别。
这个在日本当地时间周二（4月12日）中午做出的宣布意味着福岛核电站事故与1986年
苏联切尔诺贝利核辐射泄漏事故同等。
承认严重性
原子力安全委员会周一深夜已召开记者会声称，按照他们的计算，3月福岛第一核电站
发生核辐射泄漏事故后几小时内，泄漏到外部的核辐射为每小时1万放射性强度单位（1
万Terabecquerel）的非常高浓度放射性物质。
受到这个数字证实，福岛核电站辐射泄漏事故从当初政府评估的国际核能事故5级提升
到7级。
原子力安全委员会说，目前福岛核电站泄漏的核辐射程度是1放射性强度单位，相当于
当初的万分之一。
1个放射性强度单位等于1万亿个贝可（Becquerel）。

at <100 becquerel/liter, the reading won't be significant unless i carefully

I measure thyroid because its concentrate iodine (including radioactive)
