Radioactivity and waste disposal

Radioactive wastes, must for the protection of mankind be stored or disposed in such a manner that isolation from the biosphere is assured until they have decayed to innocuous levels. If this is not done, the world could face severe physical problems to living species living on this planet. Some atoms can disintegrate spontaneously. As they do, they emit ionizing radiation. Atoms having this property are called radioactive. By far the greatest number of uses …

…The most promising outlines in the near future are; 'the absorbtion of montmorillonite clay' which is comprised of natural clays that have a good capacity for chemical exchange of cations and can store radioactive wastes, 'fused salt calcination' which will neutralize the wastes and 'high temperature processing'. Even though man has made many breakthroughs in the processing, storage and disintegration of radioactive wastes, there is still much work ahead to render the wastes absolutely harmless.
