Detecting radiation is a fundamental necessity for national security, but doing so effectively and at a distance is a tall ...

In this week’s Science for All newsletter, Vasudevan Mukunth explains a new way to detect radioactive materials using ...

After emitting an alpha or beta particle, the nucleus will often still be ‘excited’ and will need to lose energy. It does this by emitting a high energy electromagnetic wave called a gamma ray.

Uranium (chemical symbol U) is a naturally occurring radioactive element. In its pure form it is a silver-coloured heavy metal, similar to lead, cadmium and tungsten. Like tungsten it is very dense, ...

Radioactivity is a part of our earth - it has existed all along. Naturally occurring radioactive materials are present in its crust, the floors and walls of our homes, schools, or offices and in the ...

JON CHASE:'Nuclear weapons, nuclear power stations 'and life-saving medical techniques, all use radioactivity. JON CHASE:'But what is it? 'Elements hold the key. JON CHASE:'Every element is ...

The Universe predominantly consists of matter made of subatomic particles such as electrons, protons, and neutrons. However, there is also a presence of antimatter. Like ordinary matter ...

This idea hinges on beta decay, a process where an unstable atomic nucleus releases excess particles, resulting in a more stable configuration. This release generates beta radiation, a stream of ...

Of the four known fundamental forces of nature, the weak nuclear force is the one with the least obvious purpose. Gravity holds stars together and keeps us on the ground. The electromagnetic force ...
