12/31/2023 0 Comments Radiation exposure x ray![]() ![]() On an annual basis, every person is exposed to a variable amount of radiation from natural sources, such as cosmic rays, and from industrial sources. Naturally occurring background radiation and modern activities such as watching TV and flying in an airplane all contribute to a lifetime exposure that is only slightly increased by medical imaging.īecause natural radiation is always present in everyday life, it is impossible to be totally shielded from it. Air travel increases exposure to cosmic radiation due to the higher altitudes and less atmospheric shielding. Every year, each person is exposed to this natural radiation and radiation from a variety of other sources, including household smoke detectors and color television sets. A small amount of radioactive material even exists naturally in our bodies. Natural radiation exposure comes from the earth in rocks and soil and from outer space in the form of cosmic rays. Other forms of radiation, such as X-rays and gamma rays, are used in a number of beneficial ways, including medicine. The most familiar form of radiation is visible light, like that produced from the sun or a light bulb.
