Smoke from a fire absorbs alpha radiation altering the ionisation and triggering the alarm. Bbc gcse bitesize types of radiation free download as pdf file pdf text file txt or read online for free. Learn more about scribd membership.

Radioactivity is a process of decay of chemical elements with time. The emission of particles is also called the emission of radiationthe radiation is emitted from the nucleus of an atom converting protons or neutrons of the nucleus into different particles. This is because the particles or rays become more spread out.
