- Because of their high energy, gamma rays are ionizing, meaning they can dislodge electrons from atoms, ultimately damaging living cells and causing a hazard to health.

Jan 28, 2020 · How does ionizing radiation affect cells? When ionizing radiation interacts with a cell, several things can happen: The radiation could pass through the cell without damaging the DNA. The radiation could damage the cell’s DNA, but the DNA repairs itself. The radiation could prevent the DNA from replicating correctly.
Gamma rays have enough energy to cause damage to living tissue, but almost all cosmic gamma rays get blocked by Earth’s atmosphere. They are highly penetrating and interacts with matter through ionization via three processes: photoelectric effect, Compton scattering, or pair production.
Oct 25, 2010 · Interactions of Radiation with Cellular Constituents. Gamma rays or x-rays interact with atoms in the cell by the photoelectric effect, Compton scattering, or pair production. In human tissue, Compton scattering is the most likely interaction.

Jul 27, 2023 · Ionizing radiation is a type of energy released by atoms that travels in the form of electromagnetic waves (gamma or X-rays) or particles (neutrons, beta or alpha). The spontaneous disintegration of atoms is called radioactivity, and the excess energy emitted is a form of ionizing radiation.
Feb 19, 2024 · Radiation can damage the DNA in cells, and high doses can lead to cancer later in life. Overview. We've been studying the effects of radiation on living tissue for more than 100 years. By measuring radiation and understanding its health effects, we can work safely around it.
X-rays and gamma rays can cause a number of other problems besides cancer. What problems occur depends on factors such as the radiation dose, the timing of the exposure, and what areas of the body are exposed.
Oct 2, 2024 · X-rays and gamma rays can pass through your body, depositing energy as they go. Internal exposure is when radioactive material gets inside the body by eating, drinking, breathing or injection (from certain medical procedures).
