放射性

Volunteers are given tiny traces of a radioactively labeled drug—too small to harm them, and typically just one-hundredth of the estimated full dose—in a drink.

志愿者服用极少量的带有放射性标记的药物（只有正常剂量的1%，因为非常少所以不会伤害到他们）。

Volunteers are given tiny traces of a radioactively labelled drug—too small to harm them, and typically just one-hundredth of the estimated full dose—in a drink.

志愿者饮用了微量的放射性元素标记的药物----剂量小到没有伤害，只有足量的百分之一。
