säteilyhaitta

Säteilyhaitta refers to the potential for harm or adverse effects caused by exposure to ionizing or non-ionizing radiation. Ionizing radiation, such as X-rays and gamma rays, has enough energy to remove electrons from atoms and molecules, which can damage biological tissues and DNA. This type of radiation is associated with increased cancer risk and other health problems. Non-ionizing radiation, like radio waves and microwaves, has less energy and is not directly capable of ionizing atoms. However, high levels of non-ionizing radiation can still cause tissue heating and other biological effects.

The level of risk from säteilyhaitta depends on several factors, including the type of radiation, the dose received, the duration of exposure, and the individual's susceptibility. Sources of radiation include natural background radiation from cosmic rays and radioactive elements in the Earth, as well as artificial sources like medical imaging equipment, nuclear power plants, and electronic devices.

Regulations and safety guidelines are in place to limit exposure to radiation and minimize säteilyhaitta. These often involve dose limits for workers and the general public, as well as safety protocols for handling radioactive materials and operating radiation-generating equipment. Public awareness and education about radiation risks are also important for promoting safe practices and informed decision-making. Understanding säteilyhaitta is crucial for evaluating the safety of various technologies and environments where radiation is present.
