To understand nuclear decay equations. How to measure the activity of radioactive sources. Spontaneously means that the process of radioactive decay can not be speeded up or slowed down by physical ...

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 ...

An alpha particle consists of two protons and two neutrons and is often described as a helium nucleus. It is not the same as a helium atom as it does not contain any electrons but it is written with ...

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 ...
