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 ...

Segment 7A: Radioactive Decay We explore the nature of radioactivity. Segment 7A: Radioactive Decay We explore the nature of radioactivity and describes the types of radioactive decay that occur.

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 ...

THE hypothesis is put forward that positive electron, neutrino, positive proton and neutron are four different quantum states of one elementary particle. Such an assumption would be trivial unless ...

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 ...
