Ephraim Fischbach, a physics professor at Purdue, was looking into the rate of radioactive decay of several isotopes as a possible source of random numbers generated without any human input.

普渡大学物理教授Ephraim Fischbach，将探测几种同位素的放射性衰变速率的方法作为一种没有人为输入因素干扰的产生随机数的可能方法。

No one knows how neutrinos could interact with radioactive materials to change their rate of decay.

没人知道中微子中微子是如何同放射性材料发生作用并改变他们的衰变速率的。

A lump of radioactive cesium-137, for example, may decay at a steady rate overall, but individual atoms within the lump will decay in an unpredictable, random pattern.

一团放射性铯137，整体以恒定的速率衰变，但是其内部单个原子的衰变是一种不可预测的随机模式。

On checking equipment in his laboratory, he was surprised to discover that the rate of radioactive decay changed before the solar flare.

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.

FORBES: Radioactive Decay Rates May Not Be Constant After All

Physicists have long held the view that the rate of breakdown - or decay - for any given radioactive substance is constant.
