I know this is Wikipedia, but I remember seeing video of the Navy
shooting the barrels to make them sink:
From 1946 to 1970, the sea around the Farallones was used as a nuclear dumping site for radioactive waste
under the authority of the Atomic Energy Commission
at a site known as the Farallon Island Nuclear Waste Dump. Most of the dumping took place before 1960, and all dumping of radioactive wastes by the United States was terminated in 1970. By then, 47,500 55 gallon steel
drum containers had been dumped in the vicinity, with a total estimated radioactive activity of 14,500 Ci
. The materials dumped were mostly laboratory materials containing traces of contamination. Much of the radioactivity had decayed by 1980.
44,000 containers were dumped at 37°37′N 123°17′W
, and another 3,500 at 37°38′N 123°08′W
The location shown on the graphic does not match the latitude and longitude given for the two dumping sites. The co-ordinates are actually further west by about 9 nm which places both sites off the continental shelf.[citation needed
] This significantly changes the potential effects on the fishery and makes any mapping and recovery effort much harder.
The exact location of the containers and the potential hazard the containers pose to the environment
Attempts to remove the barrels would likely produce greater risk than leaving them undisturbed.
Waste containers were shipped to Hunters Point Shipyard
, then loaded onto barges for transportation to the Farallones. Containers were weighted with concrete. Those that floated were sometimes shot with rifles to sink them.
In January 1951, the highly radioactive hull
of USS Independence
, which was used in Operation Crossroads
and then loaded with barrels of radioactive waste, was scuttled in the area.
I don't have a good enough connection, but I'm sure you could find the video if you like. I'm sure Fukushima had little effect on the background radiation. I would think if the seals
are dying of radiation I would suspect they are dying from the dumping of nuclear waste for over 20 years.
