Säteilybiologinen

Säteilybiologinen refers to the biological effects of radiation. This field of study investigates how ionizing and non-ionizing radiation interacts with living organisms at cellular and molecular levels. Ionizing radiation, such as X-rays and gamma rays, has enough energy to remove electrons from atoms and molecules, leading to DNA damage, cell mutations, and potentially cell death. Non-ionizing radiation, like radio waves and microwaves, has lower energy and typically affects biological tissues by causing heating.

Research in säteilybiologinen is crucial for understanding the risks associated with radiation exposure, whether from natural sources like cosmic rays and radon, or from artificial sources like medical imaging, radiation therapy, and nuclear technologies. It helps in establishing safety guidelines and developing protective measures for individuals working with or exposed to radiation.

Key areas of investigation include radiobiology, which focuses on the biological mechanisms of radiation damage and repair, and radiation protection, which aims to minimize harmful effects. Studies explore a range of outcomes, from acute radiation syndrome following high-dose exposure to long-term effects like cancer induction and genetic mutations from chronic low-dose exposure. The field also examines the potential therapeutic uses of radiation, such as in cancer treatment, where controlled radiation doses are used to destroy malignant cells.
