What is radiation BBC Bitesize?
Consequently, what is alpha radiation GCSE?
Alpha radiation consists of alpha particles. An alpha particle is identical to the nucleus of a helium atom, which comprises two protons and two neutrons .
Also, how does radiation happen? Radiation is energy that travels in the form of waves (electromagnetic radiation) or high-speed particles (particulate radiation). Particulate radiation happens when an unstable (or radioactive) atom disintegrates. Electromagnetic (EM) radiation, on the other hand, has no mass and travels in waves.
Also question is, how does radiation work Bitesize?
When visible light and high frequency infrared radiation are absorbed by the surface of the Earth, the planet's internal energy increases and the surface gets hotter. Some of this infrared radiation is transmitted through the atmosphere back out into space, and some is absorbed by greenhouse gases in the atmosphere.
What is radioactivity and why is it dangerous?
Radiation is dangerous because it can ionize, which breaks apart chemical bonds. If that happens enough inside a living cell, then the cell will be killed. With enough broken chemical “parts” they just stop working.
