“”Although dumping radioactive wastes at sea from ships is now banned, paradoxically the discharge of radioactive wastes into the sea via pipelines from land is not,” said Mike Townsley of Greenpeace. “Such ‘double standards’ are not maintained for technical or scientific reasons, but only because the operators of the nuclear reprocessing facilities in La Hague (France) and Sellafield (UK) want to save money.”
“It is cheaper for them to continue to use the sea as a radioactive garbage bin than to store this radioactive waste on land; for the nuclear industry, money comes first and the environment second”, said Mike Townsley (2).”
Dumping in the oceans is still happening as we can see from the above articles and measurements by Greenpeace as well as others. So it does a great disservice when Wikipedia reports nuclear dumping as something that happened ONLY in the past, and it is not happening anymore.
According to Wikipedia; “From 1946 through 1993, thirteen countries (fourteen, if the USSR and Russia are considered separately) used ocean disposal or ocean dumping as a method to dispose of nuclear/radioactive waste. The waste materials included both liquids and solids housed in various containers, as well as reactor vessels, with and without spent or damaged nuclear fuel.

Disposals were taken place under consideration of;
locate ideal dumping site for depth, stability and ocean current treatment of radioactive waste, solidification, containment
However some of dumping was done to dilute radioactive waste with surface water. Some containers imploded after being dumped due to the enormous pressures found in deep ocean water.
USSR, UK, Switzerland, US, Belgium, France, Netherlands, Japan, Sweden, Russia, New Zealand, Germany, Italy and Korea had dumped waste at over 100 dumping sites.

These sites are monitored by United States Environmental Protection Agency and US National Oceanic and Atmospheric Administration. So far no excess level of radionuclides were found in sample (sea water, sediments) collected in the area, except the sample taken at close location of disposed packages which contained elevated level of isotopes of caesium and plutonium.”en.wikipedia.org/wiki/Ocean_disposal_of_radioactive_waste

thanks for sharing..
Hazardous waste disposal is indeed a critical issue. So it is important to get help or service of professionals.For more information on hazardous waste services click here.
Agreed with Edward, great post. The chemicals are extremely hazardous for the environment, for marine and land life.-Land Source Container Service, Inc.City Container Services
