By far the largest source of natural radiation exposure comes from varying amounts of uranium and thorium in the soil around the world. The radiation exposure due to cosmic rays is very dependent on altitude, and slightly on latitude: people who travel by air, thereby, increase their exposure to radiation.
The four major types of radiation include alpha particles, beta particles, neutrons, and electromagnetic radiation. We are exposed to different levels of radiation in our everyday lives, including from healthcare (X-rays, CT scans, mammograms), air travel, building materials, cigarette smoking, cell phones, wearable technology, and more.
27 Ιουλ 2023 · Exposure to radiation also comes from human-made sources ranging from nuclear power generation to medical uses of radiation for diagnosis or treatment. Today, the most common human-made sources of ionizing radiation are medical devices, including x-ray machines and Computed Tomography (CT) scanners.
Additionally, some human-made radiation sources include consumer products, nuclear and coal-burning power plants, and medical uses such as nuclear medicine and computed tomography (CT). Annually, a US citizen is exposed to an average radiation dose of 6.2 millisieverts (mSv)
16 Ιουλ 2024 · One of the main effects of UV radiation is its ability to suppress the body’s immunological response to antigens. UV exposure triggers a series of reactions in the skin that may lead to local, but possibly also systemic immunosuppression.
20 Οκτ 2022 · Natural Sources. The exposure of humans to radiation from natural sources is unavoidable.
