sugárzásvédelem

Sugárzásvédelem refers to the principles and practices employed to minimize the harmful effects of ionizing and non-ionizing radiation on humans and the environment. This field is crucial in various settings, including healthcare (radiology, radiotherapy), nuclear power generation, industrial applications of radiation, and even in everyday life due to natural background radiation.

Ionizing radiation, such as X-rays, gamma rays, and alpha and beta particles, has enough energy to remove electrons from atoms and molecules, potentially causing damage to living tissues and DNA. Non-ionizing radiation, like radio waves, microwaves, and visible light, generally has lower energy but can still have biological effects, particularly at high intensities or prolonged exposures.

The core principles of radiation protection are time, distance, and shielding. Minimizing the time spent near a radiation source, increasing the distance from it, and using appropriate shielding materials (like lead for X-rays and gamma rays, or concrete for neutrons) are fundamental strategies. Personal protective equipment, such as lead aprons and dosimeters to measure radiation exposure, are also vital tools.

Regulatory bodies establish dose limits for radiation workers and the general public to ensure that exposures remain below levels considered to pose significant health risks. Ongoing research and technological advancements continue to refine radiation protection methods, aiming for ever-safer use of radiation in science, medicine, and industry.
