Gammakiirgusega

Gammakiirgusega refers to gamma radiation, a form of electromagnetic radiation with very high energy. It is produced by the radioactive decay of atomic nuclei and can also be generated by other high-energy processes such as particle collisions. Gamma rays are part of the electromagnetic spectrum, lying beyond ultraviolet radiation and X-rays, and are characterized by their short wavelengths and high frequencies.

The penetration power of gamma radiation is significant, allowing it to pass through many materials that block visible light or X-rays. This property makes it both useful and hazardous. In medicine, gamma rays are employed in diagnostic imaging techniques like PET scans and in radiation therapy to treat cancer by destroying malignant cells. Industrially, gamma radiation is used for sterilization of medical equipment and food, as well as for industrial radiography to inspect welds and materials for defects.

However, exposure to high levels of gamma radiation can be harmful to living organisms. It can damage DNA and cells, leading to increased risk of cancer and other health problems. Therefore, strict safety protocols are in place to protect individuals working with radioactive materials or in environments where gamma radiation is present. Shielding, such as thick concrete or lead, is often used to reduce exposure. The intensity of gamma radiation decreases with distance from the source.
