Säteilysäätely, also known as radiation regulation, refers to the measures and practices implemented to control exposure to ionizing and non-ionizing radiation. The primary goal of radiation regulation is to protect human health and the environment from potential harmful effects of radiation. This involves setting dose limits, establishing safety standards, and overseeing the use of radioactive materials and radiation-producing equipment.

Ionizing radiation, such as X-rays and gamma rays, can damage living cells and increase the risk of cancer. Regulations for ionizing radiation are typically established by national authorities, such as the Radiation and Nuclear Safety Authority (STUK) in Finland. These regulations cover areas like medical imaging, nuclear power, industrial radiography, and radiation protection in workplaces. They dictate how radiation sources should be handled, stored, and disposed of, as well as require monitoring of radiation levels and personnel dosimetry to ensure compliance with dose limits.

Non-ionizing radiation, including radio waves, microwaves, and visible light, generally has lower energy and is not thought to cause direct cellular damage in the same way as ionizing radiation. However, high-intensity non-ionizing radiation can cause thermal effects or other biological responses. Regulations in this area often focus on electromagnetic compatibility and the potential for interference with electronic devices, as well as setting exposure limits for devices like mobile phones and Wi-Fi equipment to prevent adverse health effects.

International organizations like the International Commission on Radiological Protection (ICRP) and the International Atomic Energy Agency (IAEA) play a significant role in developing recommendations and guidelines that inform national regulatory frameworks. Effective radiation regulation requires a multidisciplinary approach involving scientific expertise, legal frameworks, and enforcement mechanisms to ensure public safety.
