The process of releasing energy in the form of electromagnetic waves or particles from a specific source in all directions.
The phenomenon by which materials emit radiation, including both electromagnetic radiation and particle radiation, often associated with certain elements.
A characteristic of substances that possess the ability to emit radiation, which can lead to contamination or exposure to radioactive elements.
Example:
ドップラー効果はまた、一般に光と放射エネルギーにおいても見られる。
A weapon that expels liquid fuel mixed with air, igniting it to create a stream of fire intended to inflict damage on people or structures.
A device designed to project flames over a distance, primarily used in military applications for creating fire-based attacks on enemies or fortifications.
An apparatus that combines fuel and air under pressure to produce a continuous flame as a means of warfare or combat.
A characteristic of a substance that enables it to emit radiation, either naturally or as a result of artificial processes.
The property of certain materials that allows them to release energy in the form of radiation, including particle and electromagnetic radiation.
A term used to describe elements or compounds that continuously emit radiation, which can have various effects on the environment and living organisms.
A form of energy that is emitted from certain materials as a result of their atomic structure changing, which includes various types of particles and electromagnetic waves, such as alpha, beta, and gamma rays.
The phenomenon where particles and waves are released from unstable atomic nuclei, often associated with elements that continuously emit this energy in various forms.
The process through which energy in the form of rays or particles spreads outward from a source, potentially affecting other materials and living organisms in its vicinity.
Example:
