Säteilyuhkien

Säteilyuhkien refers to radiation hazards in Finnish. This term encompasses the potential dangers associated with exposure to ionizing and non-ionizing radiation. Ionizing radiation, such as gamma rays, X-rays, and alpha and beta particles, has enough energy to remove electrons from atoms and molecules, which can damage biological tissues and DNA. Sources of ionizing radiation include natural radioactive materials in the environment, medical procedures like X-rays and radiotherapy, and nuclear power plants and weapons. Non-ionizing radiation, like radio waves, microwaves, and visible light, has lower energy and generally does not have enough energy to ionize atoms. However, high-intensity non-ionizing radiation can still cause harm, for example, by heating tissues.

The risks associated with säteilyuhkien depend on several factors, including the type of radiation, the dose received, the duration of exposure, and the part of the body exposed. Acute high-dose exposures can lead to immediate health effects, such as radiation sickness. Chronic low-dose exposures are more difficult to assess but are linked to an increased risk of developing cancer over time. Protective measures are implemented to minimize exposure to radiation hazards. These include shielding, limiting exposure time, and maintaining a safe distance from radiation sources. Regulatory bodies establish dose limits for workers and the general public to ensure safety. Monitoring and surveillance programs are also in place to assess radiation levels in the environment and identify potential risks.
