Read the text and make resume of it:

The time "cures", but there is no safe spot

While people create radioactive elements, they do not have any methods to reduce their radioactivity. Only time is capable of doing so. For example, he period of semi-disintegration of carbon - 14 is 5900 years. The period of semi-disintegration of strontium - 90 is 28 years. But some parts of radiation remain forever. And it is not possible to do anything with this, except to bury the radioactive substances in а safe place. But where is it possible to find this safe place for the huge amounts of radioactive wastes, produced as а result of the production activities of the people?

No place on Earth can be considered safe enough for such kind of activity. Some time ago people thought that it was possible to place these wastes into the deepest places of the oceans, suggesting that life is not possible in those areas. But then this idea was refuted by deep underwater research done by Soviet scientists. Everywhere, where life is present radioactive substances join the biological cycle. А few hours after these materials were placed under water it is possible to trace them in living organisms. Sea-weeds and many sea animals accumulate radioactive substances in- concentrations, which are thousands of times higher than concentrations of the same substances in the surrounding water. And since some of the organisms serve as food for other ones, radioactive substances gradually come back to humans.

Some scientific and research centers study the "maximum limits of concentration" (MLС) and "maximum admissible levels" (MAL) of various radioactive elements. MLС implies certain amounts of the given radioactive substance, which may be accumulated inside human bodies without causing any harm to the health of the person. But it is well-known that any accumulation eventually causes damage. In Western countries attempts were made to determine, which dozes of radiation are tolerable and even the "maximum admissible levels" were developed, but they did not by any means solve the problem.

The international agreement on radioactive wastes burial has not yet been reached. The 1959 Monaco Conference of the International Nuclear Energy Agency lead only to disagreements among countries. "Highly radioactive" wastes are continuously thrown into the ocean, "moderately" and "low" radioactive wastes are dumped into rivers or just on the ground.
