Enterrer ? Enfouir ? Ne serait-ce pas oublier ? Comment traiter les déchets radioactifs ? L'enfouissement des déchets radioactifs dans les conditions actuelles est-il acceptable ? A-t-on préparé le démantèlement des centrales nucléaires ? Les recherches scientifiques permettent-elles, actuellement, le traitement de tous ces déchets pour les rendre inoffensifs ? Sommes-nous assez informés des dangers de toutes ces poubelles nucléaires ?
In the event of an accident, the man can be displayed(exposed) in a internal way, in particular after inhalation of particles of plutonium in suspension in the air, or after wound, even ingestion of contaminated food. Generally speaking, when the plutonium penetrates into the body, its radioactivity pulls(entails) then an irradiation of the contaminated organs.
After inhalation, dusts containing some plutonium settle in lungs according to their size(cutting). Most of the particles, of size(cutting) superior to some micrometers, quickly iron air traffics towards the digestive system and follow then the future of the ingested plutonium. The smaller particles can stay several months in the lung, before being eliminated in turn by digestive way or dissolving if the plutonium is under a soluble shape; the element is then transferred in the blood.
After wound, fragments containing some plutonium can stay in the wound and dissolve slowly to gain the blood. However, the metallic fragment quickly surrounds itself with a fibrous hull(shell) which limits this dissolution.
