säteilemä

Säteilemä is a Finnish word that translates to "radiation" in English. It refers to the emission of energy in the form of particles or waves. Radiation can be classified into two main types: ionizing and non-ionizing. Ionizing radiation has enough energy to ionize atoms or molecules by removing tightly bound electrons, while non-ionizing radiation does not have this capability.

Radiation is a natural part of the environment and is present in various forms, such as sunlight, cosmic rays, and radioactive materials found in the Earth's crust. It is also used in medical treatments, industrial processes, and scientific research. However, excessive exposure to ionizing radiation can be harmful to living organisms, as it can cause damage to cells and DNA, leading to conditions like cancer.

In Finland, the safety of radiation is regulated by the Radiation and Nuclear Safety Authority (STUK). They monitor and control the use of radiation sources and ensure that they are used safely and responsibly. The public is also informed about radiation levels and safety measures through various channels, such as news reports and educational campaigns.
