We don't know what astatine looks like, because, as Lowe put it, "that stuff just doesn't want to exist." It's so radioactive ( with a half-life measured in hours) that any large piece of it would be quickly vaporized by its own heat.

我们不知道砹看上去是什么样子的，正如劳维所说：“这玩意儿根本就是不想存在。”砹具有极强的放射性（半衰期以小时计算），任何一块稍微大一点儿的砹块都会被自身衰变释放出来的热量气化掉。

Our cube would, briefly, contain more astatine than has ever been synthesized. I say "briefly" because it would immediately turn into a column of superheated gas.

而我们这个立方体中的砹含量将在短时间内超过有史以来所有提纯出来的砹的总量，这里我强调“短时间内”，是因为这个砹块将会迅速变成一大团炽热的气体。

The retention of~ ( 211) At in blood of mice was much greater in the~ ( 211) At-IgG treated mice than in the Na~ ( 211) At treated mice, implying that the bond between the IgG and astatine was stable in vivo.

~（211）At在小鼠血液中的保留，在~（211）At-IgG处理的小鼠中比在Na~（211）At处理的小鼠中高得多，IgG-At键在体内应是稳定的。
