Nuclear Radiation _ GCSE Physics

The video tutorial explains background radiation, which comes from both natural and artificial sources. Natural sources include cosmic rays and radon gas, while artificial sources stem from nuclear power and medical X-rays. It describes three types of radiation: alpha, beta, and gamma. Alpha particles are similar to helium atoms without electrons, beta radiation involves high-energy electrons, and gamma radiation is part of the electromagnetic spectrum. The video also covers the penetration abilities of these radiations, with alpha being the least and gamma the most penetrating.

How does alpha radiation affect atomic structure according to the text?
