Study Notes
Definition of Radiation
- Radiation is the emission or transmission of energy in the form of waves or particles through space or a material medium.
- Radiation encompasses electromagnetic, particle, acoustic, and gravitational forms.
Types of Radiation
- Electromagnetic Radiation: Includes radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation.
- Particle Radiation: Includes alpha radiation, beta radiation, and neutron radiation, which all have non-zero rest energies.
- Acoustic Radiation: Includes ultrasound, sound, and seismic waves that require a physical medium for transmission.
- Gravitational Radiation: Includes gravitational waves, which are ripples in the curvature of space-time.
Radiation Categorization
- Radiation is categorized into ionizing and non-ionizing, depending on the energy of the radiated particles.
- Ionizing radiation carries more than 10 electron volts (eV) and can ionize atoms and molecules, breaking chemical bonds.
- Non-ionizing radiation has less than 10 eV and cannot ionize atoms.
- Ionizing radiation is significantly more harmful to living organisms due to its ability to create chemical changes.
- Radioactive materials emitting alpha, beta, or gamma radiation are common sources of ionizing radiation.
