Radiation in physics is a process of emission of energy in the form of waves or particles. Various types of radiation may be distinguished, depending on the properties of the emitted energy/matter, the type of the emission source, properties and purposes of the emission, etc.

Radiation by type of emission

---

• Electromagnetic radiation, a stream of photons.
  • Gamma radiation, which is high-energy electromagnetic waves.
• Gravitational radiation, a predicted consequence of general relativity.
• Particle radiation, radiation by means of particles that have a rest mass.
  • Alpha radiation, composed of the nuclei of helium-4 atoms.
  • Beta radiation, consisting of energetic electrons or positrons.
  • Neutron radiation

Work on the measurement uncertainty on solar radiation. Data from different radiometers = different results! Why???
