One of the first things that Physics students learn when they study radioactivity is the idea of the half-life. A half-life is the period of time in which it takes one-half of a given amount of a ...

Radioactive decay is the strange and almost mystical ability for one element to naturally and spontaneously transmute into another. In the process, those elements tend to emit deadly forms of ...

Radioactive material gets a bad rap, what with radiation and fallout and nuclear waste and all. But it offers some practical uses. One of the coolest (OK, maybe the coolest) is using radioactive ...

Researchers refute the assumption that the decay rate of some radioactive nuclides depends on the distance between the Earth and the Sun. PTB researchers refute the assumption that the decay rate of ...

Anomalies in the radioactive decay of beryllium-8 and helium-4 point to the existence of a new force of nature. That is the conclusion of a group of theorists in the US, who have scrutinized data from ...
