7 Ιουλ 2023 · Today, the most common artificial sources of human exposure to radiation are X-ray machines and radiopharmaceuticals used for diagnostic or radiotherapy and other medical devices. Exposure to radiation can result from natural sources (e.g. radon in homes), planned (medical, occupational) or accidental situations.

- Ionizing Radiation, Health Effects and Protective Measures
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.
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. We are exposed to ionizing radiation from natural sources in two ways: We are surrounded by naturally-occurring radioactive elements in the soil and stones, and are bathed ...
19 Μαρ 2020 · There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects. The first is an alpha particle.
The United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) identifies four major sources of public exposure to natural radiation: cosmic radiation; terrestrial radiation; inhalation; ingestion; Exposure from cosmic radiation. The earth's outer atmosphere is continually bombarded by cosmic radiation.
This fact sheet addresses the baseline sources of background ionizing radiation and other sources of radiation to which we are commonly exposed on a daily basis. Sources of Radiation. Background radiation is emitted from both natural and human-made radionuclides, or radioactive atoms. Some naturally occurring radiation comes from the atmosphere
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.
