The impact of different types of radiant energy

  • Acute radiation syndrome
  • Chronic radiation sickness
  • Local radiation injuries
  • Radiation damage in forensic against
  • The population of the globe is constantly exposed to various types of radiation. This so-called background radiation, which has two components: natural background and technical generated by human activity - technogenic background.
    Natural background due to cosmic radiation and natural radioactive substances contained in the soil, the air, in the entire biosphere. Technogenic background due to the increasing level of use of atomic energy for peaceful purposes and in the manufacture of nuclear weapons. Adverse effects of exposure result intermittent high-intensity irradiation and in the relatively long-term exposure to low doses.
    The irradiation intensity may be increased to a considerable extent during nuclear weapon tests, accidents at nuclear reactors, which lead to radioactive contamination areas, to accumulate mainly strontium-90, cesium, other long-lived isotopes and a sharp increase in radiation levels.
    The program of destruction of nuclear weapons, the creation of lasting peace without wars and violence are close and understandable to all people, especially physicians, since corresponds to their moral and professional duty.
    Scientific and practical achievements in physics, chemistry and related Sciences opened prospects for the use of ionizing radiation in industry, agriculture, biology and medicine. Radioisotopes and other radiation sources used in medical institutions for diagnosis and treatment; almost all the population is held x-ray examination. Therefore, assessment of radiation exposure from various sources of radiation is very important because it can affect the health of the population. In this regard, has acquired special urgency the issue of radiation safety and the prevention of possible radiation damage. Under this condition, on behalf of the bodies of inquest and investigation may be necessary in the relevant forensic research.
    Exposure occurs more often alpha and beta particles, gamma rays, x-rays and neutrons. In space radiation can be caused by protons and other particles at high energies. Perhaps mixed irradiation, when simultaneously affected by different types of radiation energy. For example, during nuclear explosions or for accidents at nuclear reactors can occur gamma-neutron radiation.
