radioactive decay constant

基本解释

The story begins, in a sense, in classrooms around the world, where students are taught that the rate of decay of a specific radioactive material is a constant.
這個事情要從世界各地的教室裡說起，在那裡學生學習到特定核素的衰變速率是恒定的。

But if physicists at Stanford and Purdue are correct in their findings, the whole theory of constant radioactive decay rates could be thrown out the door.

The team of physicists was investigating the possibility of using radioactive decay rates to generate random numbers, since the rate is constant but the emission of individual atoms is unpredictable, it seemed like a perfect fit.
