Radioactive contamination, also called radiological pollution, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition).
We receive internal exposure from radioactive elements which we take into our bodies through food and water, and through the air we breathe. In addition, we have radioactive elements (Potassium 40, Carbon 14, Radium 226) in our blood or bones.
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.
Radioactive Pollution is defined as the increase in the natural radiation levels caused by human activities. It is estimated that about 20% of radiation we are exposed to is due to human activities.
Pathophysiology |. Symptoms and Signs |. Diagnosis |. Prognosis |. Treatment |. Prevention |. More Information. Ionizing radiation injures tissues variably, depending on factors such as radiation dose, rate of exposure, type of radiation, and part of the body exposed. Symptoms may be local (eg, burns) or systemic (eg, acute radiation sickness).
27 Ιουλ 2023 · The spontaneous disintegration of atoms is called radioactivity, and the excess energy emitted is a form of ionizing radiation. Unstable elements which disintegrate and emit ionizing radiation are called radionuclides. All radionuclides are uniquely identified by the type of radiation they emit, the energy of the radiation, and their half-life.
10 Απρ 2024 · Radioactive contamination occurs when radioactive material is deposited on or in an object or a person. A contaminated person has radioactive materials on or inside their body. Radioactive materials released into the environment can cause contamination of: Air. Water. Surfaces. Plants and soil. Buildings. People. Animals.
