Säteilyvaikutuksista refers to the effects of radiation on living organisms and the environment. Radiation is a form of energy that travels in waves or particles and can be classified as ionizing or non-ionizing. Ionizing radiation, such as X-rays, gamma rays, and alpha particles, has enough energy to remove electrons from atoms or molecules, creating ions. This can cause damage to living cells by breaking chemical bonds and altering DNA.

The effects of radiation on living organisms can be acute or chronic. Acute effects occur rapidly and can be fatal if the dose is high enough. These include symptoms like nausea, vomiting, hair loss, and radiation sickness. Chronic effects occur over a long period of exposure and can lead to diseases such as cancer and genetic mutations. The risk of these effects increases with the amount of radiation exposure and the sensitivity of the exposed tissue.

Non-ionizing radiation, like visible light and radio waves, does not have enough energy to ionize atoms but can still have biological effects. These can include heating tissue (as with microwave radiation) or exciting molecules to produce chemical reactions (as with ultraviolet radiation).

Environmental effects of radiation include contamination of soil, water, and food, which can lead to long-term ecological damage. Radiation can also affect climate and weather patterns, although the extent of these effects is still a topic of research.

Radiation protection measures are crucial to minimize the risks associated with radiation exposure. These include time, distance, and shielding to reduce exposure, as well as regulations and safety protocols in industries that use radiation. Awareness and education about radiation and its effects are also important for public health and safety.
