Many of these wastes remain dangerously active for tens of thousands of years, while others have a life span closer to a quarter of a million years. Various methods have been used to date, but all have revealed weaknesses, forcing scientists to continue their search.
The nuclear process involves several stages, with the danger of radioactivity constantly present. Fuel for nuclear reactors comes from uranium ore, which, when mined,, spontaneously produces radioactive substances as byproducts. This characteristic of uranium ore went undetected for a long time resulting in the death, due to cancer, of hundreds of uranium miners.
The United States attempted to bury much of its radioactive waste material in containers made of steel covered in concrete and capable of holdi

An International Convention on the Dumping of Wastes at Sea was signed by ninety states in 1972 to restrict dumping toxic wastes beyond the continental shelves. It is not yet ratified, and even when it is, who will police it With the increasing of exploration and mining at sea, in all probability, the amount of waste will do.
Urgent research into the ecological balances of sea life and how they are affected by pollution is needed. As scientific knowledge stands now, we do not know how much damage the oceans can endure.
