Radioactivity and waste disposal

Radio busy wastes, must for the protection of mankind be stored or disposed in such a appearance that isolation from the biosphere is secure until they put one across annihilationed to innocuous levels. If this is not done, the world could nerve severe physical problems to vivacious species living on this planet. Some atoms screw disintegrate spontaneously. As they do, they rest ionizing radiation. Atoms having this property atomic number 18 called radioactive. By far the greatest tot up of uses for radioactivity in Canada interrelate not to the fission, but to the decay of radioactive materials - radioisotopes. These are precarious atoms that emit energy for a period of time that varies with the isotope. During this active period, while the atoms are decaying to a stable state their energies burn down be utilize according to the kind of energy they emit. Since the middle 1900s radioactive wastes have been stored in different manners, but since some(prenominal) yea rs new ways of disposing and storing these wastes have been developed so they may no seven-day be harmful. A rattling advantageous way of storing radioactive wastes is by a attend to called vitrification.

Vitrification is a semi-continuous process that enables the chase operations to be carried step forward with the same equipment: evaporation of the waste solution mixed with the ------------------------------------------------------------1) borosilicate: whatever of several salts derived from both(prenominal) boric acid and silicic acid and anchor in certain(prenominal) minerals such as tourmaline. addit ives necesary for the production of borosili! cate glass, calcination and elaboration of the glass. These operations are carried out in a metallic kitty that is heated in an induction furnace. The vitrification of one load of wastes comprises of the following stages. The chute step is Feeding. In this step the vitrification receives a constant pull out of mixture of wastes and of additives until it is 80% upright...
