säteilytyypit

Säteilytyypit refers to different classifications of radiation. Radiation can be broadly categorized into ionizing and non-ionizing radiation. Ionizing radiation possesses enough energy to remove an electron from an atom or molecule, a process known as ionization. Examples include alpha particles, beta particles, gamma rays, and X-rays. These types of radiation can damage living tissue and are often associated with radioactive decay and medical imaging.

Non-ionizing radiation does not have enough energy to ionize atoms. This category includes radio waves, microwaves, infrared radiation, visible light, and ultraviolet radiation. While generally considered less harmful than ionizing radiation, high-intensity non-ionizing radiation can still cause effects such as heating of tissues.

Another way to classify radiation is by its origin. Natural radiation originates from sources in the environment, such as cosmic rays from space and terrestrial radiation from naturally occurring radioactive elements in the Earth's crust. Artificial radiation is produced by human activities, including medical procedures like X-rays and CT scans, nuclear power plants, and certain industrial processes. Understanding these different säteilytyypit is crucial for assessing potential risks and implementing appropriate safety measures.
