Radioactive Pollution

The radioactive pollution is the pollution generated by the Radioactivité. It can have several origins:

  • Natural (ex: Radon)
  • Industrial:
    • for the nuclear electrical production, there is pollution during the electrical production, of the reprocessing of waste, the storage of the radioactive waste
    • in the medical field which also creates a certain number of radioactive waste
    • in a certain number of creative industries of radioactive waste (others that electrical production)
    • others
  • Militaire: in particular during test of atomic bombs which were made for a long time in altitude, but also by the wrecks of tanks left in the desert after being destroyed by fusion Eutectique of the shells with Uranium impoverished: Iraqi children played in these wrecks!
  • Medical: the use of radioactive substances for medical examinations (ex: scintiscanning) pourraît to contaminate water via the urines of the patients, causing a weak but significant variation of the measured radioactivity;
  • Accidental: at the time of Nuclear accident like Tchernobyl, a certain number of radioactive elements can disperse in the atmosphere and/or the ground and/or the hydrographic network (Fleuve S, ground water, etc).

Radioactive pollution is harmful for the man: indeed, the radioelements have one more or less long lifespan and disintegrate by emitting dangerous radiations. When radioelements are fixed in the human body, they can be dangerous even if the total quantity of emitted radiations is relatively weak, because they reach the surrounding cells in a very concentrated way, being able to create tumors (mutagen character of radiations). The human body can have to fix radioelements in several manners:

  • By breathing: so gas radon particles disintegrate whereas they are in the lungs, they are transformed into element heavy which are fixed, and continue to them " life radioactive" and their harmful emissions until their end-of-life.
  • By the food: if a ground is contaminated by a radioactive pollution, the plants and the animals eating these plants run the risk of a radioactive contamination. Certain plants are particularly radio-accumulating: lavender, mushrooms. Certain bodies are also more sensitive: for example, the thyroid one fixes iodine, this is why in the event of radioactive contamination, one distributes iodine pastilles not contaminated to the residents in order to saturate the thyroid one with iodine " saine" and to avoid its contamination by radioactive iodine.
