WebSep 20, 2024 · A person’s average effective radiation dose from natural sources is somewhere around 3mSv per year. Those living at higher altitudes and frequent flyers have slightly higher average doses. When looking at x-ray radiation doses, it can be helpful to compare them to the equivalent amount of natural background radiation for perspective. WebFor x rays of the energy encountered in CT, the radiation weighting factor is equal to 1.0. Thus, for CT, the absorbed dose in a tissue, in Gy, is equal to the equivalent dose in Sv.

Webgamma rays: Gamma rays are high‐energy electromagnetic radiation (photons) emitted in an attempt by the radionuclide to become stable, i.e., radioactive decay. Gamma rays have moderate‐to‐high penetrating power, are often able to penetrate deep into the body, and generally require some form of shielding, such as lead or concrete.
